2 USA V. HAMILTON
SUMMARY **
Criminal Law
The panel affirmed Robert Hamilton’s conviction and
sentence for being a felon in possession of a firearm and
ammunition and possessing a firearm in furtherance of a
drug-trafficking crime.
Law enforcement had specific information connecting
Hamilton to an unlawful shooting. When they located and
tried to stop him two weeks after the shooting, he ran. The
officers chased Hamilton on foot for several blocks, and
observed him reaching for his waistband. An officer ordered
Hamilton to show his hands and get on the ground, but
Hamilton continued running. A second police car stopped
in front of Hamilton, and officers tackled him to the
ground. Hamilton was handcuffed and arrested. After the
arrest, officers searched Hamilton and found a gun,
marijuana, scales, and $6,692 in cash.
The panel affirmed the district court’s denial of
Hamilton’s motion to suppress.
• Hamilton asserted that the officers’ attempt
to stop him was unlawful because they
intended to conduct an arrest, not merely an
investigatory stop, from the outset. The
panel explained that the officers’ intent
when they initially approached Hamilton is
immaterial because he ran before the

USA V. HAMILTON 3
officers could do anything other than order
him to stop, and they did not actually seize
him. Thus, in the officers’ initial contact,
the Fourth Amendment was not triggered.
• Hamilton contended that the officers’ initial
approach was improper because one of them
falsely stated that there was a warrant for his
arrest. The panel explained that even if this
was a lie rather than a mistake, there was no
constitutional violation because the officers
had reasonable suspicion that Hamilton was
involved in the shooting, which Hamilton
does not dispute. The officers therefore had
a lawful basis to stop and question him
without a warrant. Additionally, the
officers, whose actions and words made
clear that they were approaching in an
official investigatory capacity, were not
misrepresenting their purpose. And because
Hamilton did not stop and no arrest
occurred, the officers did not exceed their
authority. There is no basis on which to
conclude the officers’ initial approach was
unreasonable.
• Hamilton argued that his arrest was
unlawful because the officers did not have
probable cause to believe he had committed
a crime. The panel noted that flight is not
per se suspicious. But here, the officers had
specific evidence that connected Hamilton
to the unlawful shooting, there was no
ambiguity about the officers’ identities, they
4 USA V. HAMILTON
called Hamilton by name and ordered him to
stop, and they observed him reaching for his
waistband while fleeing. Therefore, when
the officers tackled Hamilton to stop his
flight, they had reason to conclude that there
was a fair probability that he had committed
a crime, and the arrest was lawful.
The panel held that the district court did not abuse its
discretion in instructing the jury that the evidence was
obtained legally and that the jury may not speculate as to
whether the police had improper motives in arresting and
searching Hamilton. When viewed in the context of the
entire trial, the instruction did not improperly guide the jury
or intrude on its fact-finding role.
The panel held that the district court did not abuse its
discretion in applying a sentencing enhancement under
U.S.S.G. § 2K2.1(b)(6)(B) for possessing a gun in
connection with another felony offense.
District Judge Oliver concurred. He wrote separately to
add some factual and legal context to the discussion
regarding probable cause, and to indicate two areas where
his analysis varies from the majority—the analysis applied
to determine when deception and falsehoods by officers are
permissible consistent with the Fourth Amendment, and the
relevance of the fact that the arrest took place in a high crime
area.

OPINION
FORREST, Circuit Judge:
Flight from law enforcement can be suggestive of
wrongdoing and give rise to probable cause when coupled
with specific reasons to suspect that the person fleeing may
have engaged in criminal conduct. Here, law enforcement
had specific information connecting Defendant Robert
Hamilton to an unlawful shooting in downtown San
Francisco. When they located and tried to stop Hamilton two
weeks after the shooting, he ran. The totality of
circumstances surrounding Hamilton’s flight gave the
officers probable cause to arrest him. Therefore, we affirm
the district court’s denial of Hamilton’s motion to suppress
the evidence obtained from his arrest. We also reject
Hamilton’s jury-instructions and sentencing-enhancement
challenges and affirm his conviction and sentence.
6 USA V. HAMILTON
I. BACKGROUND
A. Valentine’s Day Shooting
Around 2:00 a.m. on February 14, 2021, officers from
the San Francisco Police Department responded to reports of
a shooting in the Tenderloin neighborhood of San Francisco.
Sergeant Habib interviewed the three victims who were shot.
The first victim stated that he saw a “small Black man”
approach a Black woman and begin arguing with her. The
victim then saw the man take the woman to his four-door car.
Soon after, the victim heard five gunshots. The victim
described the man’s clothing, said that he had no facial hair,
and estimated his age and height. The victim relayed that he
“believe[d]” that the man and woman were related.
The second victim similarly reported seeing a Black man
shoot a gun from a four-door car. And the third victim said
that he saw a black four-door car double parked around the
time of the shooting, but he could not provide a description
of the shooter.
Sgt. Habib reviewed surveillance footage of the
shooting, which showed a taxi arrive at the intersection of
the shooting. A woman exited the taxi and crossed the street
out of the camera’s frame. A few seconds later, a black
Hyundai appeared and parked behind the taxi. The driver of
the Hyundai—a Black man—exited the car and walked out
of the camera’s frame in the same direction as the woman.
One minute later, the man and the woman re-entered the
camera’s frame and appeared to be arguing. The man
grabbed the woman and pulled her into the passenger seat of
the Hyundai. He then got into the driver’s seat and, while
driving away, appeared to shoot a gun out of the driver’s side
window.
USA V. HAMILTON 7
The surveillance video captured the taxi’s car number
and the black Hyundai’s license plate. Sgt. Habib contacted
the taxi company and learned the name and address of the
woman the taxi dropped off at the intersection of the
shooting. He then checked for other residents at the woman’s
address and learned that Hamilton lived at that location. Sgt.
Habib reviewed Hamilton’s mug shot and related
information and, based on the shooter’s stature in the
surveillance video, believed that Hamilton may have been
the shooter. A record check also revealed that Hamilton had
prior firearm-related convictions.
A search of the Hyundai’s license plate showed that it
was registered to a rental company. Sgt. Habib contacted the
rental company and learned that the Hyundai was rented out
for a several-day period that included the day of the
shooting. Screenshots from the Hyundai’s dash camera
showed a Black man in the driver’s seat and a Black woman
in the passenger seat on February 8. Sgt. Habib noted that
the man captured on the dash camera looked similar to
Hamilton’s mug shot. GPS data confirmed that the Hyundai
was at the intersection of the February 14 shooting just
before the shooting occurred.
Sgt. Habib showed the surveillance footage and the dash
camera image to two officers who had previously
encountered Hamilton. The officers identified the man in the
surveillance footage as Hamilton and the woman as
Hamilton’s mother. Both officers also identified the driver
in the dash camera image as Hamilton.
B. Hamilton’s Arrest
Around 4:00 p.m. on February 27, 2021, an officer
involved in the shooting investigation, Sgt. Payne, spotted
Hamilton several blocks away from where the Valentine’s
8 USA V. HAMILTON
Day shooting occurred. He advised other officers in the area
that Hamilton was wanted for the Valentine’s Day shooting,
that the gun used in the shooting was missing, and that it was
“highly likely” that Hamilton had it on his person. Officers
knew this to be a high-crime area where drug sales,
shootings, and other crimes routinely occur. Sgt. Payne told
the officers that Hamilton was a 25-year-old Black man
wearing a black jacket, black pants, and a red shirt. And Sgt.
Habib gave the officers two photos of Hamilton.
One officer in the area saw a Black man approximately
25 years old wearing the clothes that Sgt. Payne described.
The officer also noted that the man matched the photos of
Hamilton. Several officers then met up and “devised a plan
to take Hamilton into custody.”
Shortly thereafter, two officers pulled up to Hamilton in
their patrol car. One officer told Hamilton that the officers
needed to speak with him. The other officer called
Hamilton’s name and told him that there was a warrant for
his arrest and ordered him to stop. Hamilton looked at the
officers and immediately ran. The officers chased Hamilton
on foot for several blocks, and they observed him reaching
for his waistband. Based on this action, the officers believed
that Hamilton had a gun. An officer ordered Hamilton to
show his hands and get on the ground, but Hamilton
continued running.
A second police car stopped in front of Hamilton, and
officers tackled him to the ground. Hamilton was handcuffed
and arrested. After the arrest, officers searched Hamilton and
found a gun, marijuana, scales, and $6,692 in cash.
USA V. HAMILTON 9
C. District Court Proceedings
On May 13, 2021, Hamilton was indicted with one count
of being a felon in possession of a firearm and ammunition
in violation of 18 U.S.C. § 922(g)(1). The grand jury later
returned a superseding indictment adding a charge of
possessing a firearm in furtherance of a drug-trafficking
crime in violation of 18 U.S.C. § 924(c)(1).
Hamilton moved to suppress all the evidence obtained
from his arrest and subsequent searches, arguing that the
officers lacked probable cause to arrest him. The district
court denied Hamilton’s motion. The district court
determined that when the officers initially approached
Hamilton on February 27, they had reasonable suspicion (but
not probable cause) to believe that Hamilton was involved in
the Valentine’s Day shooting. The district court also
determined that the officers’ suspicion developed into
probable cause to arrest when they saw Hamilton flee and
subsequently reach for his waistband.
At trial, over Hamilton’s objection, the district court
instructed the jury that the evidence presented was obtained
legally and directed jurors to not speculate as to whether the
police had improper motives in arresting and searching
Hamilton. The jury convicted Hamilton of possessing a
firearm and ammunition but acquitted him of possessing a
firearm in furtherance of a drug-trafficking crime. Hamilton
moved for a new trial, arguing that the jury instruction
vouched for the arresting officers and affected the jury’s
consideration of whether the gun was planted. The district
court denied this motion, concluding that Hamilton waived
his objection to the jury instruction, that the instruction was
not erroneous, and that any error was harmless.
10 USA V. HAMILTON
During sentencing, the district court found that when
Hamilton was arrested, he possessed the gun in connection
with dealing marijuana. Based on this finding, the court
applied a four-level sentencing enhancement under U.S.S.G.
§ 2K2.1(b)(6)(B) for possessing a gun in connection with
another felony offense. The court sentenced Hamilton to 27
months’ imprisonment.
II. DISCUSSION
A. Motion to Suppress
Hamilton argues that the evidence found on him when he
was arrested must be suppressed because the officers lacked
probable cause for arrest and his arrest was executed in an
unreasonable manner. Both arguments fail.
The Fourth Amendment protects “against unreasonable
searches and seizures.” U.S. Const. amend. IV. “[T]he
ultimate touchstone of the Fourth Amendment is
reasonableness.” United States v. Anderson, 101 F.4th 586,
591 (9th Cir. 2024) (en banc) (internal quotation marks and
citation omitted). We consider the totality of the
circumstances in assessing whether law enforcement acted
reasonably. See Samson v. California, 547 U.S. 843, 848
(2006). We review a district court’s denial of a motion to
suppress de novo, and we review its factual findings for clear
error. United States v. Fisher, 56 F.4th 673, 682 (9th Cir.
2022).
1. The Officers’ Initial Approach
The district court concluded that the officers had a lawful
basis to stop Hamilton because they reasonably suspected
USA V. HAMILTON 11
that he was involved in the Valentine’s Day shooting.1
Hamilton does not dispute this. Nonetheless, Hamilton
asserts that the officers’ attempt to stop him was unlawful
because they intended to conduct an arrest, not merely an
investigatory stop, from the outset.
Under the circumstances presented, the officers’ intent
when they initially approached Hamilton is immaterial
because he ran before the officers could do anything other
than order him to stop. Thus, in their initial approach, the
officers only attempted a seizure. They did not actually seize
Hamilton. See United States v. Smith, 633 F.3d 889, 893 (9th
Cir. 2011) (“[T]here is no seizure without actual submission;
otherwise, there is at most an attempted seizure . . . .”
(quoting Brendlin v. California, 551 U.S. 249, 254 (2007))).
And where no seizure occurred during the officers’ initial
contact with Hamilton, the Fourth Amendment was not
triggered. California v. Hodari D., 499 U.S. 621, 626 (1991)
(holding that a seizure does not occur when the subject does
not yield after an officer’s show of authority); Smith, 633
F.3d at 892 (holding that an attempted stop cannot violate
the Fourth Amendment if there was no seizure).
Moreover, the Supreme Court has instructed that
“outside limited contexts such as an ‘inventory search or
administrative inspection . . . an officer’s motive [does not]
invalidate[] objectively justifiable behavior under the Fourth
Amendment.’” Kentucky v. King, 563 U.S. 452, 464 (2011)
(quoting Whren v. United States, 517 U.S. 806, 812 (1996));
see also United States v. Delgadillo-Velasquez, 856 F.2d
1292, 1295 (9th Cir. 1988) (“The proper focus when
1
We need not and do not address whether the district court erred in
concluding that the officers lacked probable cause to arrest Hamilton for
the Valentine’s Day shooting based on their pre-arrest investigation.
12 USA V. HAMILTON
determining coerciveness or restraint sufficient to constitute
an arrest or detention is not on the subjective belief of the
agents. Rather we review the situation from the perspective
of the person seized.”). Hamilton does not dispute that the
officers had “objectively justifiable” grounds to conduct an
investigatory stop based on reasonable suspicion. King, 563
U.S. at 464. And if Hamilton had not fled and the officers
had immediately arrested him, a different analysis would
apply. But that is not what happened, and we must decide
this case based on the facts as they are, not as they might
have been.
Hamilton further contends that the officers’ initial
approach was improper because one of them falsely stated
that there was a warrant for his arrest. While the officer’s
statement about the existence of an arrest warrant was
incorrect, the record does not establish whether it was a lie
or a mistake. But even assuming it was a lie, there was no
constitutional violation. Officers are not categorically
prohibited from using deception in investigations. See, e.g.,
Lewis v. United States, 385 U.S. 206, 208–09 (1966)
(recognizing that “it has long been acknowledged” that law
enforcement can use deceptive tactics in their investigations
subject to the protections in the Bill of Rights); United States
v. Carona, 660 F.3d 360, 365–66 (9th Cir. 2011) (same). But
deception may be unreasonable if it is used “to gain access
to places and things [officers] would otherwise have no legal
authority to reach.” United States v. Ramirez, 976 F.3d 946,
954 (9th Cir. 2020) (quoting United States v. Alverez-Tejeda,
491 F.3d 1013, 1017 (9th Cir. 2007)). For example, where a
suspect knows that he is dealing with law enforcement,
officers are prohibited from abusing their position to gain
access to evidence “by affirmative[ly] or deliberate[ly]
USA V. HAMILTON 13
misrepresent[ing] the nature of [their] investigation.” United
States v. Little, 753 F.2d 1420, 1438 (9th Cir. 1984).
Here, the officers had reasonable suspicion that
Hamilton was involved in the Valentine’s Day shooting,
which Hamilton does not dispute. Therefore, they had a
lawful basis to stop and question him without a warrant.
Florida v. Royer, 460 U.S. 491, 498 (1983); cf. Alverez-
Tejeda, 491 F.3d at 1017 (concluding officers did not
improperly gain access where “they already had the
authority to seize [the evidence and the defendant]; their lies
didn’t have the effect of expanding their ostensible authority
beyond the scope of their actual authority” (emphasis
added)). Additionally, the officers’ actions and words made
clear that they were approaching Hamilton in an official
investigatory capacity. They were not misrepresenting their
purpose. And because Hamilton did not stop and no arrest
occurred, the officers did not exceed their authority. In short,
there is no basis on which to conclude that the officers’ initial
approach was unreasonable.
Hamilton suggests that upholding his arrest despite the
officers’ false statement would allow law enforcement to go
on fishing expeditions—randomly approaching people on
the street to manufacture probable cause when they flee.
That is hyperbole and not what happened here. The officers
did not contrive a situation to get Hamilton to flee. Hamilton
chose to run knowing who the officers were, that they knew
who he was, and that he had been ordered to stop.
Hamilton’s choice to run is properly considered in assessing
the totality of circumstances that surrounded the officers’
actions. See United States v. Brown, 925 F.3d 1150, 1155–
56 (9th Cir. 2019).
14 USA V. HAMILTON
2. Hamilton’s Arrest
Hamilton also argues that his arrest was unlawful
because the officers did not have probable cause to believe
he had committed a crime.
Probable cause justifying a warrantless arrest exists
where, “under the totality of the facts and circumstances
known to the arresting officer, a prudent person would have
concluded that there was a fair probability that the suspect
had committed a crime.” United States v. Struckman, 603
F.3d 731, 739 (9th Cir. 2010) (emphasis added) (internal
quotation marks and citation omitted). Probable cause can
develop during the course of an event. See Illinois v.
Wardlow, 528 U.S. 119, 125–26 (2000). The Supreme Court
has instructed that “[h]eadlong flight—wherever it occurs—
is the consummate act of evasion: It is not necessarily
indicative of wrongdoing, but it is certainly suggestive of
such.” Id. at 124. Even where an “individual has a right to
ignore the police and go about his business, . . . [f]light, by
its very nature, is not ‘going about one’s business’; in fact, it
is just the opposite.” Id. at 125.
That said, flight is not per se suspicious. See Brown, 925
F.3d at 1155. Consistent with the Fourth Amendment’s
totality standard, “[t]here may be circumstances where a
person’s flight has a perfectly innocent and reasonable
explanation” and thus does not reasonably engender
suspicion. Smith, 633 F.3d at 894. And if the reason for the
suspect’s flight is ambiguous—that is, it could have been to
evade law enforcement or it could have been for some other
innocent purpose—the flight itself cannot justify an arrest.
See Wong Sun v. United States, 371 U.S. 471, 482–84
(1963); Brown, 925 F.3d at 1155–56.
USA V. HAMILTON 15
Relying on Wong Sun and Brown, Hamilton argues that
his flight was ambiguous and could not establish probable
cause for arrest. These cases are distinguishable. In Wong
Sun, officers were investigating a tip that someone named
“Blackie Toy” was selling drugs out of a laundromat. 371
U.S. at 473–74. An officer went to the laundromat and told
the defendant, who answered the door, that he wanted
laundromat service. Id. at 474. The defendant stated that the
laundromat was closed and tried to shut the door. Id. The
officer then identified himself as a narcotics officer, and the
defendant slammed the door and ran down the hall. Id. The
Court concluded that the reason for the defendant’s flight
was ambiguous because the officer had not “adequately
dispelled the misimpression engendered by his own ruse” or
established that the defendant was the person suspected of
selling drugs before the defendant ran. Id. at 482–83. 2
In Brown, the defendant was engaged in “presumptively
lawful” conduct—carrying a concealed firearm—when
police approached him to investigate an anonymous tip
describing a “black man ‘[with] a gun’” and he fled. 925 F.3d
at 1153. There was no indication that the defendant had or
was engaged in any criminal activity. Id. Thus, we concluded
that “the totality of the circumstances” did “not add up to
enough: no reliable tip, no reasonable inference of criminal
behavior, no police initiative to investigate a particular crime
in an identified high crime area, and flight without any
previous attempt to talk to the suspect.” Id. at 1157. We
further stated that “racial dynamics in our society” provided
a potential innocent explanation for the defendant’s flight
2
Wong Sun was decided before Terry, so it did not analyze whether law
enforcement had reasonable suspicion of criminal activity.
16 USA V. HAMILTON
where there was no indication of criminal activity that would
warrant investigation. Id.
In contrast, here the officers had specific evidence that
connected Hamilton to an unlawful shooting less than two
weeks before they tried to stop him. There was no ambiguity
about the officers’ identities, unlike in Wong Sun, and they
called Hamilton by name and ordered him to stop.
Hamilton’s arguments about racial disparities in policing
cannot overcome the circumstances at issue or
“commonsense judgments and inferences about human
behavior.” Wardlow, 528 U.S. at 125. It is reasonable to
infer, given the totality of circumstances, that Hamilton ran
to evade law enforcement. See id. at 124; Struckman, 603
F.3d at 740 (“In assessing probable cause, we take into
account reasonable inferences.”). Indeed, this case is
analogous to Smith, where we held that the defendant’s flight
reasonably suggested wrongdoing where he was in a high-
crime area, the officer activated his siren and clearly
identified himself before ordering the defendant to stop, the
defendant understood that the officer was talking to him, and
then the defendant fled. 633 F.3d at 891; see also Sibron v.
New York, 392 U.S. 40, 66–67 (1968) (“[D]eliberately
furtive actions and flight at the approach of strangers or law
officers are strong indicia of mens rea, and when coupled
with specific knowledge on the part of the officer relating
the suspect to the evidence of crime, they are proper factors
to be considered in the decision to make an arrest.”); United
States v. Cruz, 910 F.2d 1072, 1077 (3d Cir. 1990) (“Flight
at the approach of law enforcement officers, when coupled
with specific knowledge relating the suspect to evidence of
a crime, is a proper factor to be considered in the decision to
make an arrest.”).
USA V. HAMILTON 17
Additionally, the officers also observed Hamilton
reaching for his waistband while fleeing. Hamilton argues
that this action was also ambiguous and not a proper basis
for suspecting wrongdoing because it could have indicated
that his pants were falling down. This is unpersuasive.
Officers “need not rule out the possibility of innocent
conduct” in forming suspicion of criminal activity. United
States v. Valdes-Vega, 738 F.3d 1074, 1078–79 (9th Cir.
2013) (quoting United States v. Arvizu, 534 U.S. 266, 277
(2002)). Reasonable inferences can be relied upon.
Struckman, 603 F.3d at 740. And where the officers had
specific evidence connecting Hamilton to a recent unlawful
shooting, knew that the gun from the shooting had not been
recovered, and also knew that Hamilton had a prior firearm
offense and might be armed, the officers could reasonably
infer that Hamilton reaching for and clutching his waistband
indicated that he was armed. Cf. Pennsylvania v. Mimms,
434 U.S. 106, 111–12 (1977) (concluding that an officer may
reasonably believe an individual is armed based on
perceiving a bulge in a jacket).
For these reasons, when the officers tackled Hamilton to
stop his flight, they had reason to conclude that there was a
“fair probability that [Hamilton] had committed a crime,”
Struckman, 603 F.3d at 739, and the district court correctly
concluded that Hamilton’s arrest was lawful. Therefore, we
affirm the district court’s denial of Hamilton’s motion to
suppress.
B. Jury Instructions
Next, Hamilton argues that the district court erred by
instructing the jury that the evidence was obtained legally,
and the jury may not speculate as to whether the police had
improper motives in arresting and searching Hamilton.
18 USA V. HAMILTON
As a preliminary matter, the Government contends that
Hamilton waived any objection to the jury instructions
because his counsel stated that the “instruction as to the
legality of the stop was sufficient to advise the jury,” and
because counsel indicated that the defense was satisfied with
the jury instructions. Alternatively, the Government argues
that Hamilton forfeited his objection to the jury instructions
because he failed to specify the grounds for this objection
before his motion for a new trial. Neither argument is
persuasive. The Government’s waiver argument ignores
Hamilton’s objections to the challenged instruction during
trial. See United States v. Perez, 116 F.3d 840, 845 (9th Cir.
1997) (waiver occurs where a defendant “affirmatively acted
to relinquish a known right”). Likewise, Hamilton did not
forfeit his jury-instruction challenge because, as in Shorter
v. Baca, he “objected to the . . . instruction at trial, albeit on
a different ground, and in a motion for new trial.” 895 F.3d
1176, 1183 (9th Cir. 2018).
On the merits, “we review the district court’s
formulation of its instructions for abuse of discretion.”
United States v. Mikhel, 889 F.3d 1003, 1056 (9th Cir. 2018).
“[A] district court abuses its discretion in formulating
instructions if ‘the instructions—taken as a whole and
viewed in context of the entire trial—were misleading or
confusing, inadequately guided the jury’s deliberations, or
improperly intruded on the fact finding process.’” Id. at 1058
(citation omitted).
Here, the instruction that Hamilton challenges stated in
full:
The evidence in this case was obtained
legally. It is not for you to consider or to
speculate whether any evidence presented to
USA V. HAMILTON 19
you was obtained improperly or in violation
of law.
You also may not speculate as to whether the
police had any improper motives in arresting
or searching the defendant on February 27,
2021.
Hamilton argues that this instruction intruded on the jury’s
fact-finding role, undermining his defense that the officers
planted the gun, and improperly vouched for the officers
who arrested Hamilton. But Hamilton’s requested
instruction also removed the legality of the search from the
jury’s purview. 3 And when viewed in context of the entire
trial, the court’s instruction did not improperly guide the jury
or intrude on its fact-finding role. See id. As the district court
explained, other instructions emphasized that the
Government had to prove that Hamilton knowingly
possessed the gun and made clear that issue was for the jury
to decide. Additionally, the instruction that the jury “may not
speculate as to whether the police had any improper motives
in arresting or searching the defendant” did not credit the
officers’ trial testimony. See United States v. Weatherspoon,
410 F.3d 1142, 1146 (9th Cir. 2005). Rather, it directed the
jury not to inquire into why the officers stopped Hamilton,
3
Hamilton’s requested instruction read:
Whether or not the arrest and search of the defendant
was lawful is a legal matter that has been resolved by
the Court and that is not within the scope of your role
as jurors. It is not for you to consider or to speculate
whether any evidence presented to you was obtained

as Hamilton recognized at trial. Thus, the district court did
not abuse its discretion in instructing the jury.
C. Sentencing
Finally, Hamilton argues that the district court erred by
applying a four-level sentencing enhancement under
U.S.S.G. § 2K2.1(b)(6)(B) for possessing a gun “in
connection with another felony offense.” “We review the
district court’s factual findings for clear error . . . and its
application of the Guidelines to the facts for abuse of
discretion.” United States v. Harris, 999 F.3d 1233, 1235
(9th Cir. 2021).
The district court found that Hamilton was dealing
marijuana on the day he was arrested. The record supports
this finding. Hamilton had a large amount of marijuana, two
scales, and over $6,000 in cash with him when he was
arrested. The district court also found, based on a
preponderance of evidence, that Hamilton possessed the gun
in connection with dealing marijuana, noting the expert
testimony from trial that people involved in drug trafficking
“often need and have a weapon in order to protect the cash
that they have, the drugs that they have.” The district court’s
findings were not clearly erroneous. See United States v.
Syrax, 235 F.3d 422, 427 (9th Cir. 2000). Accordingly, the
district court did not abuse its discretion in applying
§ 2K2.1(b)(6). See United States v. Grimaldo, 993 F.3d
1077, 1082 (9th Cir. 2021).
AFFIRMED.
USA V. HAMILTON 21
SOLOMON OLIVER, JR., Senior District Court Judge,
concurring.
I agree with the majority that the trial court’s denial of
Defendant’s motion to suppress should be affirmed. I also
agree with the majority that the district court did not abuse
its discretion in instructing the jury, or in applying a
sentencing enhancement. I write to add some factual and
legal context to our discussion regarding probable cause, and
to indicate two areas where my analysis varies from the
majority. The first centers on the analysis applied to
determine when deception and falsehoods by officers are
permissible consistent with the Fourth Amendment. The
second is in regard to whether the fact that the arrest took
place in a high crime area was relevant. Otherwise, I join in
the majority opinion, and neither of these differences causes
me to disagree with the majority opinion that there was
probable cause for the arrest.
The district court concluded that the officers initially
only had sufficient evidence to conduct a Terry stop of
Defendant. See Terry v. Ohio, 392 U.S. 1 (1968). The
officers had some evidence that Defendant committed the
crime as discussed by the majority; however, the vantage
point of the surveillance camera made it difficult to identify
the shooter. The three victims of the shootings were only
able to give vague descriptions of the shooter. The officers
who identified Defendant as the person in the video could
only do so based on Defendant’s “stature” because of the
poor quality of the video. It is undisputed that no warrant
was obtained during the almost two weeks that elapsed
between the shooting and Defendant’s arrest. The district
court concluded, based on the information the officers
obtained during their investigation and the facts and
22 USA V. HAMILTON
circumstances surrounding Defendant’s flight from police,
that there was probable cause to arrest Defendant.
The majority concluded, as did the trial court, that the
evidence previously gathered by the police department was
sufficient to conduct an investigatory stop of Defendant
pursuant to Terry. Defendant conceded this point. However,
the record indicates that, when the officers confronted
Defendant, they were ready to arrest him, not merely
investigate him pursuant to Terry. According to a declaration
of Sergeant Habib, the lead investigator, he ordered the
officers to “bring Hamilton into custody” and “arrest
Hamilton based on [his] investigation.” To “facilitate the
arrest,” he sent them mugshots of Hamilton. When the
officers pulled up to Hamilton in their patrol cars, one officer
said, “Hey come here. We need to talk to you.” This was
followed in seconds by another officer who said, “Robbie
Hamilton, there is a warrant for your arrest. I need you to
stop!” Hamilton then took off running. After Hamilton was
apprehended, he asked, “What’s going on?” and an officer
responded, “Like I announced to you as soon as I saw you,
there is a warrant for your arrest.”
As the majority states, law enforcement can, under some
circumstances, use deception or falsehoods in carrying out
its responsibilities. The majority also acknowledges that
there are some limits on the circumstances when they may
do so. For example, in the context of a Terry stop, officers’
falsehoods or deception could cause an investigatory
detention to cross the line beyond a permissible Terry stop.
This would occur if the measures employed “would cause a
reasonable person to feel that he or she will not be free to
leave after brief questioning–i.e., that indefinite custodial
detention is inevitable[,]” and that the measures were not
justified based on the government’s interests in officer safety
USA V. HAMILTON 23
and investigating crime. United States v. Guzman-Padilla,
573 F.3d 865, 884 (9th Cir. 2009) (citations omitted).
Here, despite having the evidence that would justify a
Terry stop, as acknowledged by Defendant, the officers did
not intend, nor did they execute, a Terry stop. Such a stop
would arguably have been justified based on the evidence
regarding Defendant’s alleged involvement in criminal
activity that took place almost two weeks earlier. However,
such a stop would not have been justified based on suspicion
that he was involved in criminal activity when they spotted
him. Indeed, Defendant was not in the area where the crime
at issue took place, and he was not exhibiting any behavior
suggesting he was engaged in other criminal activity at that
time. Further, he was not posing any known danger to the
officers or anyone else, such as to justify detaining him in
aid of a Terry stop. Based on the facts, as established in the
record, Defendant would reasonably have concluded that the
officers were not just seeking to talk to him, but to arrest him
pursuant to a warrant. He would likely not have felt free to
leave after brief questioning. This might have been the case
regardless of whether the announcement by the particular
officer was a deliberate falsehood or mistake, based on the
fact that he was told there was a warrant for his arrest. That
said, I agree with the majority that, if Defendant had not fled
and was immediately arrested, we would be performing a
different analysis, namely whether the officers had gone
beyond the bounds of an investigatory stop in arresting him.
In light of the fact that Defendant fled, we must now
view the totality of the circumstances leading up to his arrest
in order to determine whether there was probable cause to
arrest him. In doing so, we still must evaluate whether the
officers’ misrepresentation that they had a warrant—when
they did not—caused a violation of Defendant’s rights under
24 USA V. HAMILTON
the circumstances herein. Though my analysis differs from
the majority in part, I agree that no constitutional violation
occurred here. While it is true that officers may use
deception in certain circumstances to carry out their law
enforcement responsibilities, we have made it clear that,
“[l]aw enforcement does not have carte blanche to use
deception to effect a search and seizure. A ruse that reveals
the officers’ identity as law enforcement but misrepresents
the purpose of their investigation so that the officers can
evade limitations on their authority raises serious Fourth
Amendment concerns.” United States v. Ramirez, 976 F.3d
946, 955 (9th Cir. 2020).
Here, the officers clearly indicated that they were law
enforcement and represented that they had authority to make
an arrest pursuant to a warrant, which they did not then
possess. It is only because they were unsuccessful in
arresting Defendant at that point that one can conclude there
was no Fourth Amendment violation. I disagree with the
majority’s statement that the officers “were not
misrepresenting their purpose.” On the contrary, they had no
authority to arrest him immediately, if at all, pursuant to a
Terry stop. Thus, they were misrepresenting their purpose.
If they had arrested him without probable cause on the
representation that they had a warrant, and obtained
incriminating evidence, there might well have been a Fourth
Amendment violation.
I also agree with the majority that what happened during
Defendant’s flight after being confronted by the officers,
together with what the officers had gathered during their
investigation, gave them probable cause to arrest him. The
officers had evidence that he was involved in the Valentine’s
Day shooting, which would have allowed them to perform
an investigatory stop. The majority opinion also points to the
USA V. HAMILTON 25
fact that Defendant was fleeing when arrested and that this
took place in a high crime neighborhood. Further, while
fleeing from the officers, Defendant tugged at his waistband,
which suggested to the officers that he was carrying a
weapon. It is my view that what Defendant did during flight
is more significant than the fact of his fleeing. After all,
running, when confronted by the police, is not always
sufficient to establish probable cause. As the majority
acknowledges, there may be a “perfectly innocent and
reasonable explanation” for flight. Smith, 633 F.3d at 894.
Further, the court in Brown found that there was no probable
cause to arrest when a man fled from officers seeking to
investigate an anonymous tip describing a “black man
‘[with] a gun’”; there was, under the totality of the
circumstances, no indication of activity warranting
investigation. There, we found that “racial dynamics in our
society” might serve as an innocent explanation for the
suspect’s flight. Here, there was more evidence supporting
probable cause than in Brown, including the evidence
gathered during Sergeant Habib’s investigation and
Defendant’s tugging at his waistband while fleeing.
However, I would give little weight to the fact that
Defendant was arrested in a high crime area. We have noted
that, “[t]he citing of an area as ‘high crime’ requires careful
examination by the court, because such a description, unless
properly limited and factually based, can easily serve as a
proxy for race or ethnicity.” United States v. Montero-
Camargo, 208 F.3d 1122, 1138 (9th Cir. 2000). The cases
where we have given weight to the fact that the person was
arrested in a high crime area while fleeing officers usually
involved the officers’ observance of suspicious activity of a
type they were investigating in that neighborhood. That was
not the case here. The crime for which they were
26 USA V. HAMILTON
investigating Defendant occurred almost two weeks prior in
an entirely different neighborhood. There is little evidence
to suggest that the neighborhood in which Defendant was
arrested should be accorded any significant weight in
determining probable cause in this case. Nevertheless, the
other evidence is sufficient to support a finding of probable
cause.
For all of the foregoing reasons, I would affirm the
district court in respect to all issues raised on appeal.
