The Honorable J. Michael Seabright, United States District Judge for
the District of Hawaii, sitting by designation.
2 USA V. IN
SUMMARY **
Criminal Law
The panel reversed the district court’s order granting
Larry Seng In’s motion to suppress a gun found in his car
during a traffic stop, and remanded for trial.
In argued that the officers’ actions, in particular their
decision to handcuff him, escalated a valid Terry stop into
an unlawful de facto arrest because the officers handcuffed
him before they had probable cause to believe that he was
prohibited from possessing the gun.
Considering the totality of the circumstances, the panel
held that the traffic stop did not turn into a de facto
arrest. The officers had a sufficient and reasonable basis to
fear for their safety, justifying their decision to handcuff In
so that their safety was assured during their investigation.

OPINION
GOULD, Circuit Judge:
Larry Seng In (“In”) was charged in a federal indictment
with being a felon in possession of a firearm in violation of
18 U.S.C. §§ 922(g)(1) and 924(a)(2) after a gun was found
in his car during a traffic stop. In moved to suppress the gun
in district court, contending that it was obtained as a result
of an unlawful de facto arrest. In did not challenge the
officers’ initial traffic stop as an unlawful Terry stop.
Instead, In argued that the officers’ actions, in particular
their decision to handcuff him, escalated a valid Terry stop
into an unlawful de facto arrest because the officers
handcuffed him before they had probable cause to believe
that he was prohibited from possessing the gun.
The district court referred the motion to a magistrate
judge. The magistrate judge held an evidentiary hearing and
prepared a report and recommendation to the district court,
concluding that In was not subject to a de facto arrest without
probable cause because the intrusive means of effecting the
Terry stop, including handcuffing, were justified under the
circumstances. The district court rejected the magistrate
judge’s recommendation and granted In’s motion to
4 USA V. IN
suppress, holding that the gun was obtained as a result of an
unlawful de facto arrest without probable cause. The United
States (“the Government”) moved for reconsideration, and
the district court denied the motion. The Government
appealed the district court’s order granting In’s suppression
motion, and we now must decide whether the traffic stop
became a de facto arrest. We have jurisdiction under
18 U.S.C. § 3731. We hold that the traffic stop did not turn
into a de facto arrest, and we reverse the district court.
BACKGROUND
On the evening of March 4, 2020, Las Vegas
Metropolitan Police Department (“LVMPD”) Enforcement
Bike Squad Officers Haley Andersen, Daniel Diaz, and
Timothy Nye engaged in a traffic stop on bicycle near Las
Vegas Boulevard (“the Strip”) in Las Vegas, Nevada.
Officers Andersen, Diaz, and Nye saw a car with a taillight
out and a California license plate parked in a red-curb no-
parking zone about fifty feet from the Strip. In was seated
in the driver’s seat of the car. Officer Diaz walked up to the
driver’s-side window, requesting In’s driver’s license,
registration, and insurance. The encounter was recorded on
body cam video from Officer Diaz and Officer Andersen.
While Officer Diaz spoke with In, Officer Andersen
shone her flashlight into the interior of In’s car and
discovered a Glock on the backseat passenger-side floor of
the car. Officer Andersen stated to the other officers that
there was a Glock in the backseat, and she told Officer Diaz
to tell In to keep his hands up. Officer Diaz ordered In to get
out of the car. In started collecting his documents before
Officer Diaz told him to stop reaching for anything in the car
and to put his hands up. In set the papers down and raised
his hands. Officer Diaz then opened the car door, put his
USA V. IN 5
hand on In’s wrist, unbuckled In’s seatbelt, and pulled In out
of the car.
After In was pulled out of the car, Officer Diaz held In
against the closed backdoor of the car while holding In’s
hands behind his back. Officer Diaz asked In, “Do you have
any weapons on you?” and In said, “No.” Officer Andersen
next asked, “There any weapons in the car?” and In said,
“No.” Officer Diaz then began patting down In. While In
was being patted down, Officer Andersen asked, “Have you
ever been arrested,” and In answered, “Yeah, in California.”
Officer Andersen then asked, “For what?” and In responded
“For marijuana,” to which Officer Andersen said, “What
else?” and In responded, “That’s It.”
Officer Diaz then began handcuffing In. While In was
being handcuffed, Officer Andersen asked: “You have no
weapons in your car?” to which In responded “No.” The
handcuffs being used by Officer Diaz made a ratcheting
sound, indicating they were being tightened, as Officer
Andersen asked “Why is there a Glock back there? You
don’t know now?” In said he had left the shooting range,
and Officer Diaz responded, “Did you? In some sandals? Do
we look new to you?” Officer Andersen told In that he had
to answer honestly or he would be in a lot of trouble.
Officer Andersen asked In, “Are you a felon?” to which
In responded, “No.” Officer Andersen then asked In if the
gun belonged to him, and he responded “Yeah.” Officer
Andersen asked, “Why are you so nervous right now?” to
which In responded, “Because I didn’t do nothing except sit
in my car.” Officer Andersen explained that the officers had
reasonable suspicion to stop In because he was parked in a
red zone for an unreasonable amount of time and had a
taillight out. Officer Diaz then walked In, handcuffed, to the
6 USA V. IN
curb. Officer Andersen asked, “You never been arrested out
here?” and In responded, “No, I’ve never got in trouble in
Las Vegas, I never come to Las Vegas.”
Officer Andersen then called LVMPD’s records office
from her cell phone to determine whether In had warrants or
convictions in Nevada. Meanwhile, Officer Diaz read In his
Miranda rights. In asked if he was getting arrested, and
Officer Diaz responded, “No, I, we—we like to read you
your rights, that way you understand before we go ahead and
talk to you.” Officer Diaz asked In what he was arrested for
in California, and In responded that he had a grand theft on
a person, but that he thought it would no longer be on his
record because it had been more than seven years.
While In stood handcuffed on the sidewalk, Officer Diaz
asked if they could search the car, and In said “Yeah.”
However, when Officer Diaz told Officer Nye that In gave
them consent to search the car, Officer Nye stopped Officer
Diaz from searching the car, telling Officer Diaz: “Whoa,
whoa, whoa, let’s hang on to that, for a second, even if we
have consent. He’s in cuffs, right?” Officer Diaz responded,
“Yeah, but you still have a firearm, that’s still an officer
safety thing,” but Officer Nye shook his head no and
rhetorically asked Officer Diaz, “Is he in the car right now?
Before we let him go, we can do that, but let’s find out if
there’s anything that she,” pointing to Officer Andersen,
“finds out before we go in. You hear what I’m saying?”
After several minutes, a fourth officer, Sergeant Leung,
arrived in a police car. Officer Andersen had been told by
LVMPD’s records office that In did not have a criminal
history or active warrants in Nevada. Officer Andersen said
to Sergeant Leung, “I’m gonna Triple I him,” referring to a
non-routine process used to obtain interstate history records.
USA V. IN 7
Sergeant Leung asked if In was prohibited from carrying a
firearm, and Officer Andersen said, “that why—I’m Triple-
I’ing him, I don’t know yet.” Officer Andersen later testified
that she believed running the Triple I check was necessary
because In said that he had been arrested in California and
was not truthful at points during the encounter.
Using the Triple I check, the officers confirmed that In
had prior felony convictions in California. The officers then
obtained a telephonic search warrant from a state court judge
to search In’s car and recovered the gun.
DISCUSSION
A. Standard of Review
We review de novo a district court’s decision on a motion
to suppress, and we review the underlying factual findings
for clear error. United States v. Zapien, 861 F.3d 971, 974
(9th Cir. 2017); United States v. Crawford, 372 F.3d 1048,
1053 (9th Cir. 2004) (en banc). “Whether a seizure exceeds
the bounds of an investigatory stop and becomes a de facto
arrest is reviewed de novo.” United States v. Edwards,
761 F.3d 977, 981 (9th Cir. 2014) (cleaned up) (citing
United States v. Miles, 247 F.3d 1009, 1012 (9th Cir. 2001)).
B. In Was Not Subject to an Arrest Requiring
Probable Cause
The Government asked us to reverse the district court’s
order granting In’s suppression motion because the officers’
use of handcuffs during the traffic stop was reasonable under
the circumstances, and did not escalate the encounter from a
valid investigative stop into a de facto arrest. We agree.
The Fourth Amendment to the United States
Constitution protects individuals from “unreasonable
8 USA V. IN
searches and seizures” by the government. U.S. Const.
amend. IV. The Fourth Amendment permits “two categories
of police seizures”: (1) Terry stops, i.e., “brief, investigative
stop[s]” when police officers “have reasonable suspicion
that the person apprehended is committing or has committed
a criminal offense”; and (2) “full-scale arrests,” which
require probable cause at the time of arrest that the person
being arrested has committed a crime. Reynaga
Hernandez v. Skinner, 969 F.3d 930, 937–38 (9th Cir. 2020)
(internal quotation marks omitted). “During a Terry stop
motivated by reasonable suspicion, the officer may ask
investigatory questions, but the scope of the detention must
be carefully tailored to its underlying justification.” Id. at
938 (internal quotation marks omitted).
“[A]t some point,” an investigative stop “can no longer
be justified as an investigative stop,” and turns into an
unconstitutional de facto arrest. United States v. Sharpe,
470 U.S. 675, 685 (1985). To determine whether a Terry
stop becomes a de facto arrest, we consider the totality of the
circumstances, including the “severity of the intrusion, the
aggressiveness of the officer’s actions, and the
reasonableness of the officer’s methods under the
circumstances.” Reynaga Hernandez, 969 F.3d at 940
(citing Washington v. Lambert, 98 F.3d 1181, 1188–89 (9th
Cir. 1996)). When considering the reasonableness of the
officer’s methods under the circumstances, we consider
whether the officer had “sufficient basis to fear for his [or
her] safety to warrant the intrusiveness of the action taken.”
United States v. Edwards, 761 F.3d 977, 981 (9th Cir. 2014).
This “inquiry is undertaken . . . from the perspective of law
enforcement, while bearing in mind that the purpose of
a Terry stop is to allow the officer to pursue his investigation
USA V. IN 9
without fear of violence.” Id. (internal quotation marks
omitted).
The use of “especially intrusive means” of effecting
Terry stops has been held permissible in certain
circumstances, including:
(1) where the suspect is uncooperative or
takes action at the scene that raises a
reasonable possibility of danger or flight;
(2) where the police have information that the
suspect is currently armed; (3) where the stop
closely follows a violent crime; and
(4) where the police have information that a
crime that may involve violence is about to
occur.
Reynaga Hernandez, 969 F.3d at 940–941 (quoting
Washington, 98 F.3d at 1189 (footnotes omitted)).
“Handcuffing as a means of detaining an individual does not
automatically escalate a stop into an arrest, but it
substantially aggravates the intrusiveness of an otherwise
routine investigatory detention and is not part of a typical
Terry stop.” Id. at 941 (internal quotation marks omitted).
In this case, the officers’ decision to handcuff In made
the traffic stop more intrusive than a typical Terry stop, but
the use of handcuffs was reasonable under the circumstances
and did not convert the stop into an arrest. Officer Andersen
saw an unsecured gun on the floor of the backseat of In’s car
seconds into the traffic stop, and when Officer Andersen
asked In whether he had a gun in his car after In was ordered
out of his car, In lied and said “No.” While In was physically
cooperative with the officers up until this point, he became
uncooperative when he answered untruthfully the officer’s
10 USA V. IN
question about having a gun in his car, and his response
reasonably raised the possibility that the stop could turn
extremely dangerous due to the information gap that existed
between the officers and In and the unsecured gun on the
floor of the backseat of the car. See Washington, 98 F.3d at
1189. The safety risks posed by the stop were amplified
because the stop occurred about fifty feet from the Strip, a
densely populated tourist area, and the officers were
patrolling on bicycles without the protection of a patrol car
if the traffic stop turned dangerous.
Because the officers were patrolling on bicycles, they
could not place In inside a patrol car while conducting their
investigation. If the officers had not handcuffed In, they
would have had to rely on their ability to physically
overpower In if he attempted to reach for the gun that was
visible and loose on the floor of the backseat of the car.
Although In did not actually reach for the exposed gun, the
question is whether officers had a sufficient basis to fear for
their safety to warrant the intrusiveness of the actions taken.
Edwards, 761 F.3d at 981. Considering the totality of the
circumstances, we hold that the officers had a sufficient and
reasonable basis to fear for their safety, justifying their
decision to handcuff In so that their safety was assured
during their investigation. The officers had good reason to
handcuff In to prevent him from being able to access the
unsecured gun on the floor of the backseat. The officers
were eliminating the possibility that In could gain access to
the unsecured gun. That conduct properly protected both the
officers and the general public. And this is true even though
Nevada is an open carry state. See Nev. Const. art. I, § 11.
Because the officers’ conduct was reasonable under the
circumstances, the Terry stop did not escalate into a de facto
arrest without probable cause.
USA V. IN 11
CONCLUSION
In was not subjected to an arrest requiring probable
cause. We reverse the district court’s order granting In’s
suppression motion and remand the case for trial.
REVERSED AND REMANDED.
