GRUENDER, Circuit Judge.
This appeal concerns a suit brought under 42 U.S.C. § 1983 and Minnesota
law by Sumaya Aden (“Ms. Aden”) as next of kin and trustee of the estate of Isak
Aden (“Aden”). Defendants—the City of Eagan and eight individual officers—
appeal the district court’s partial denial of their motion for summary judgment based
on qualified and official immunity. We reverse, finding that the officers are entitled
to qualified and official immunity and that the City of Eagan is not subject to Monell
liability.
I. Background
Shortly after 6:00 p.m. on July 2, 2019, Isak Aden’s ex-girlfriend called 911
to report that, while she and Aden were sitting in her car, Aden had pointed a gun at
her and ordered her to drive away from her residence. As they neared the Eagan
Outlet Mall, she turned into the oncoming traffic lane to attract attention, stopped
the car, and ran away from the vehicle. Aden fled into a nearby wooded area.
Shortly afterwards, a bystander reported hearing a gunshot come from the wooded
area where Aden had run. Aden later admitted to negotiators that his firearm had
discharged when he accidentally dropped it.
Around 6:45 p.m., officers found Aden crossing a road into an industrial
parking lot that abutted a commercial building. Aden held the gun to his head as he
walked. He eventually sat down on the parking lot curb with his back to the building,
facing an empty parking lot. His gun remained aimed at his head. The officers

-- 2 of 11 --

pointed their guns at Aden, ordered him to put his gun down, and started negotiating
with Aden using a public address system. At 7:08 p.m., Aden finally set the gun
down near his right foot but then picked it up again just a few minutes later.
Over time, police officers and SWAT teams from multiple cities responded to
the scene. They were equipped with tactical body armor, helmets, assault weapons,
less-lethal weapons, bullet-proof and bullet-resistant ballistic shields, and three
armored vehicles. Officers confirmed that the area was clear of bystanders. Four
snipers kept their rifles trained on Aden. Altogether, over eighty officers from eight
different police forces were present.
At 7:25 p.m., a SWAT team member took over negotiations from inside an
armored vehicle. After an hour and a half, Aden again placed his gun on the
pavement, this time between his legs. Shortly thereafter, officers delivered a cell
phone to Aden by approaching him in an armored vehicle and tossing down a
cardboard box that contained the cell phone. Negotiations continued via phone. At
9:59 p.m., officers estimated that the gun was about three feet to Aden’s right. At
10:03 p.m., Aden moved slightly closer to the gun and officers estimated that he was
about a foot away from the gun. At 10:31 p.m., officers estimated that Aden was
about a foot and a half away from the gun. Aden repeatedly refused to surrender and
told officers that he was “not willing to go to jail tonight.”
Meanwhile, the command officers worked on a tactical plan to apprehend
Aden. The officers planned to use the element of surprise to seize him while he was
separated from his gun. Some officers would throw flashbang grenades at Aden to
disorient him, while others would fire forty-millimeter less-lethal foam bullet rounds
at his left side. The plan anticipated that Aden would react to his left—away from
the gun on his right—so that the arrest team would have a chance to rush in and
apprehend him. Other officers stood ready to provide lethal cover for the arrest team.
Police Chief Roger New approved the arrest plan. He later testified that he wanted
to take advantage of Aden being separated from his weapon. He also testified he

-- 3 of 11 --

was concerned Aden might flee with a firearm and that the police did not have a
secure perimeter.
At 10:37 p.m., as Aden spoke on the phone with negotiators, officers launched
the tactical plan. Three flashbangs exploded close to Aden as officers opened fire
with foam bullets, striking Aden in his left side. Rather than falling to the left and
away from the gun, Aden reacted to his right—towards the gun—with the cell phone
still in his left hand. He grabbed the gun with his right hand and began to raise it.
Before the gun was raised to knee height, officers deployed lethal rounds. As Aden
fell backwards, the pistol discharged, firing downwards into the ground. In total,
five officers fired twelve lethal rounds, resulting in the eleven gunshot wounds that
killed Aden. All lethal rounds were fired within 3.73 seconds of Aden picking up
his gun. A squad car camera captured the incident on video.
Ms. Aden, Aden’s next-of-kin and trustee of his Estate, sued various cities
and officers under § 1983 and Minnesota law, arguing that the officers’ actions
constituted an excessive use of force under the federal and Minnesota constitutions
and was a tort under Minnesota law. During litigation, the parties stipulated to
dismiss the Defendant Cities of Bloomington, Burnsville, and Edina, as well as
Defendants Sergeant Maksim Yakovlev and Jane and John Does. The remaining
defendants—the City of Eagan, the three supervisory officers who developed and
approved the tactical plan (Chief Roger New, Lieutenant Andrew Speakman, and
Sergeant Corey Cardenas), and the five officers who fired lethal rounds (Jacob
Peterson, Matthew Ryan, Daniel Nelson, Anthony Kiehl, and Adam Stier)—moved
for summary judgment based on qualified and official immunity. The district court
granted in part, dismissing a substantive due process claim and dismissing the
excessive use of less-lethal force claim as it applied to the lethal-force defendants.
Otherwise, the district court declined to dismiss, finding that the officers were not
entitled to either federal qualified immunity or Minnesota official immunity and that
the City of Eagan may be liable under Monell.

II. Discussion
Defendants appeal the district court’s denial of qualified immunity, its finding
that the City of Eagan may be subject to Monell liability, and its denial of Minnesota
official immunity. Summary judgment is appropriate when “the movant shows that
there is no genuine dispute as to any material fact and the movant is entitled to
judgment as a matter of law.” Fed. R. Civ. P. 56(a). Though we ordinarily “lack
jurisdiction to hear an immediate appeal from a district court’s order denying
summary judgment,” we have “limited authority to review the denial of qualified
immunity through an interlocutory appeal under the collateral order doctrine.”
Langford v. Norris, 614 F.3d 445, 455 (8th Cir. 2010) (internal quotation marks and
alteration omitted).
A. Qualified Immunity
We first address whether the officer defendants are entitled to qualified
immunity. We review a denial of qualified immunity de novo, viewing the record
in the light most favorable to the plaintiff and drawing all reasonable inferences in
her favor. See Dunn v. Does 1-22, 116 F.4th 737, 745 (8th Cir. 2024). “Qualified
immunity gives government officials breathing room to make reasonable but
mistaken judgments” and “protects all but the plainly incompetent or those who
knowingly violate the law.” Ashcroft v. al-Kidd, 563 U.S. 731, 743 (2011) (internal
quotation marks omitted). “To determine whether a defendant is entitled to
dismissal on the basis of qualified immunity, we consider (1) whether the official’s
conduct violated a constitutional right; and (2) whether the violated right was clearly
established.” Stanley v. Finnegan, 899 F.3d 623, 627 (8th Cir. 2018) (internal
quotation marks omitted). “Denial of qualified immunity will be affirmed if a
genuine issue of material fact exists as to whether a reasonable officer could have
believed his actions to be lawful.” Nance v. Sammis, 586 F.3d 604, 609 (8th Cir.
2009) (internal quotation marks omitted).

The Fourth Amendment’s prohibition against “unreasonable searches and
seizures” includes the “right to be free from excessive force in the context of an
arrest.” U.S. Const. amend. IV; Brown v. City of Golden Valley, 574 F.3d 491, 499
(8th Cir. 2009). Whether the force used was objectively unreasonable—and, thus,
constitutionally excessive—is a legal question that requires us to consider “the
totality of the relevant circumstances.” Westwater v. Church, 60 F.4th 1124, 1128
(8th Cir. 2023). “What is objectively reasonable under the particular circumstances
is evaluated from the perspective of a reasonable officer on the scene . . . and turns
on those facts known to the officer at the precise moment he effectuated the seizure.”
Cole ex rel. Est. of Richards v. Hutchins, 959 F.3d 1127, 1132 (8th Cir. 2020)
(internal quotation marks and alterations omitted). Relevant factors include “the
severity of the crime at issue, whether the suspect poses an immediate threat to the
safety of the officers or others, and whether he is actively resisting arrest or
attempting to evade arrest by flight.” Graham v. Connor, 490 U.S. 386, 396 (1989).
“The use of force is least justified against a nonviolent misdemeanant who does not
flee or actively resist arrest and poses little threat to officers or the public.” Kohorst
v. Smith, 968 F.3d 871, 876 (8th Cir. 2020). However, “[a]n officer is entitled to use
the force necessary to effect an arrest,” and even “[w]hen a suspect is passively
resistant, somewhat more force may reasonably be required.” Id. We first consider
the supervisory officers who approved the tactical plan and the use of less-lethal
force. We next consider the officers who deployed lethal force.
1. Less-Lethal Force
Ms. Aden argues that the supervisory officers violated Aden’s constitutional
right to be free from excessive force when they authorized the tactical plan and the
use of less-lethal force against Aden. We disagree; the supervisory defendants are
entitled to qualified immunity because their tactical plan reasonably addressed the
threat Aden posed. First, the officers reasonably suspected Aden had committed a
serious crime. See Graham, 490 U.S. at 396. Domestic assault with a firearm occurs
when the defendant intends “to cause fear in another of immediate bodily harm” and
a “firearm was used in any way during the commission of the assault.” Minn. Stat.

§ 609.2242 (2023). Given what the girlfriend originally told the 911 operator—that
Aden had pointed a gun at her and ordered her to drive away—the officers
reasonably suspected Aden had committed domestic assault with a firearm.1
Second, Aden was actively resisting arrest. See Graham, 490 U.S. at 396. He
refused to move out of reach of his loaded gun, refused to surrender, and stated that
he was “not willing to go to jail tonight.” Third, Aden posed an immediate threat.
Id. He had acted erratically all evening, admitted that his gun had discharged when
he was in the wooded area, refused to surrender his weapon or to meaningfully
cooperate with the negotiators, and within the past hour moved closer to his gun. In
such a “tense, uncertain, and rapidly evolving” situation, Graham, 490 U.S. at 397,
the officers reasonably designed a tactical plan—centering around the use of
flashbangs and foam bullets as forms of less-lethal force—to address the threat that
Aden posed and effectuate his arrest. Therefore, because they did not violate a
constitutional right, the supervisory defendants are entitled to qualified immunity.
The district court denied qualified immunity to the supervisory defendants
because it found that genuine issues of material fact existed—namely, whether Aden
posed an immediate, “meaningful[]” threat. But the opposing “facts” cited by the
district court—the testimonies of expert witnesses that the tactical plan was
unreasonable and that “[t]here was no emergency” compared with the testimonies of
officers who were concerned Aden would pick up his gun—are not facts at all but
only inconsistent explanations for why the officers acted. This disagreement
constitutes a legal dispute about the reasonableness of the officers’ actions, not a
factual dispute about what occurred. See, e.g., Westwater, 60 F.4th at 1129 n.1
(“whether force used was objectively reasonable or constitutionally excessive is a
1 Despite what she told the 911 operator, Aden’s girlfriend had a different story
at her home later that evening. She told an officer that Aden had not pointed the gun
at her but that she had known it was in his waist band. She could not say when she
had seen the gun or explain how she knew it was in his waistband. She also said she
had never seen Aden with a weapon before and had never known him to be violent
but that he had a short temper. Given her seeming uncertainty and that victims of
domestic violence often recant, see United States v. Farmer, 567 F.3d 343, 347 (8th
Cir. 2009), the officers reasonably credited her original testimony.

question of law”). And, as discussed, based on the undisputed facts, the officers’
actions were reasonable.
Certainly, the officers might have chosen another course of action. But “the
Constitution requires only that the seizure be objectively reasonable, not that the
officer pursue the most prudent course of conduct as judged by 20/20 hindsight
vision.” See Retz v. Seaton, 741 F.3d 913, 918 (8th Cir. 2014) (internal quotation
marks omitted). Qualified immunity gives law enforcement “breathing room to
make reasonable but mistaken judgments.” Ashcroft, 563 U.S. at 743. We will not
engage in “Monday-morning quarterbacking” and “impose liability simply because
the officers did not choose a better available method.” See Retz, 741 F.3d at 918.
Under the totality of the circumstances, the tactical plan was not objectively
unreasonable and, thus, was not a constitutionally excessive use of force.
2. Lethal Force
Ms. Aden argues that the lethal-force defendants violated Aden’s
constitutional right to be free from excessive force when they deployed deadly force.
“It is reasonable for an officer to use deadly force if he has probable cause to believe
that a suspect poses a threat of serious physical harm to the officer or others.” Rogers
v. King, 885 F.3d 1118, 1121 (8th Cir. 2018) (internal quotation marks omitted).
Objective reasonableness is not a factual question—it is a matter of law. See
Westwater, 60 F.4th at 1129 n.1. “Generally, an individual’s mere possession of a
firearm is not enough for an officer to have probable cause to believe that individual
poses an immediate threat of death or serious bodily injury; the suspect must also
point the firearm at another individual or take similar menacing action.” Cole, 959
F.3d at 1132 (internal quotation marks omitted). However, officers need not wait to
act until they are staring down the barrel of a loaded gun. See Rogers, 885 F.3d at
1121-22 (finding that officers reasonably perceived a threat of serious physical harm
when defendant raised gun to shin-level). “Simply reaching for a loaded gun is
enough to create a substantial risk of serious bodily injury to another person.” United
States v. Hill, 583 F.3d 1075, 1078 (8th Cir. 2009) (internal quotation marks and

-- 8 of 11 --

-9-
alteration omitted) (holding that defendant’s attempts to retrieve loaded firearm
during struggle with officers created substantial risk of serious physical injury).
“Additionally, before using deadly force, an officer should, when feasible, provide
a warning.” Cole, 959 F.3d at 1133 (internal quotation marks and alteration
omitted).
Here, the lethal force defendants are entitled to qualified immunity because
their conduct did not violate Aden’s constitutional right to be free from the use of
excessive force. They had probable cause to believe that Aden posed an immediate
and serious threat of bodily injury. Knowing that Aden had behaved erratically and
dangerously throughout the afternoon and evening, the officers deployed lethal force
when they witnessed Aden reach for and raise his loaded gun. As he raised his gun,
it discharged into the ground. At that time, at least seven officers were near Aden
and not within an armored vehicle. The defendant officers reasonably perceived that
Aden posed a threat of serious bodily harm and responded almost immediately—all
shots were fired within 3.73 seconds of Aden picking up his gun. This was a “split-
second judgment[].” See Graham, 490 U.S. at 397. Further, Aden was on notice
that his possession of a loaded gun could be perceived as a threat. The officers had
warned Aden several times throughout the evening that his gun posed a threat. See
Cole, 959 F.3d at 1133. Altogether, the use of lethal force was objectively
reasonable.
The district court found that a genuine factual dispute existed regarding
whether Aden pointed his gun at the officers and thus, whether the officers were in
immediate threat of serious harm. It found that “a jury could reasonably conclude”
the use of lethal force was objectively unreasonable, given that Aden had not yet
raised the gun above his knee and the officers on the scene were armed and wearing
body armor. We disagree. First, the entire exchange was captured on video,
providing undisputed facts. Second, regardless of whether Aden pointed his gun at
the officers, he reached for a loaded gun and began to raise it. The officers
reasonably perceived this as a “menacing action.” See Cole, 959 F.3d at 1132;
Rogers, 885 F.3d at 1121-22 (where officers acted reasonably in deploying deadly

-- 9 of 11 --

-10-
force when defendant raised gun to shin-level). And third, a bullet poses a threat,
see, e.g., Billingsley v. City of Omaha, 277 F.3d 990, 995 (8th Cir. 2002), regardless
of whether officers are armed or wearing body armor—as most on-duty officers
presumably are. Altogether, we can discern no genuinely disputed issue of material
fact.
In sum, because they did not violate a constitutional right, the lethal force
defendants are entitled to qualified immunity.
B. Monell Liability
We next address whether the City of Eagan is subject to Monell liability under
§ 1983. Ms. Aden’s sole remaining theory for Monell liability is based on Police
Chief New’s authorization of the tactical plan. “Absent a constitutional violation by
an employee, there can be no § 1983 or Monell liability.” Stearns v. Wagner, 122
F.4th 699, 704 (8th Cir. 2024) (internal quotation marks and alteration omitted). The
supervisory officers did not commit a constitutional violation; therefore, the City of
Eagan is not subject to Monell liability.
C. Minnesota Official Immunity
Finally, we address the denial of Minnesota official immunity for Ms. Aden’s
state law claims against both the officer defendants and the City of Eagan. “In
Minnesota the official immunity doctrine provides that a public official charged by
law with duties which call for the exercise of his judgment or discretion is not
personally liable to an individual for damages unless he is guilty of a willful or
malicious wrong.” Birkeland ex rel. Birkeland v. Jorgensen, 971 F.3d 787, 792 (8th
Cir. 2020) (internal quotation marks and alteration omitted). “In the context of
official immunity, ‘willful’ and ‘malicious’ are synonymous, and the Minnesota
Supreme Court has defined malice as ‘nothing more than the intentional doing of a
wrongful act without legal justification or excuse, or, otherwise stated, the willful
violation of a known right.’” Brown, 574 F.3d at 500-01 (quoting Rico v. State, 472

-- 10 of 11 --

-11-
N.W.2d 100, 107 (Minn. 1991)) (internal quotation marks omitted). We have
already concluded that none of the officer defendants violated a constitutional right.
Necessarily, therefore, the defendants could not have committed a “willful violation
of a known right,” id., and are also entitled to official immunity under Minnesota
law.
Because the officers are entitled to official immunity, the City of Eagan is also
entitled to vicarious official immunity. “[V]icarious official immunity protects the
government entity from suit based on the official immunity of its employee.”
Wiederholt v. City of Minneapolis, 581 N.W.2d 312, 316 (Minn. 1998) (en banc).
Thus, the City of Eagan is entitled to vicarious official immunity insofar as its
employees are entitled to official immunity. Therefore, we reverse the denial of
official immunity to all the defendants.
III. Conclusion
For the foregoing reasons, we reverse the district court’s partial denial of the
defendants’ motion for summary judgment and remand for entry of it based on
qualified and official immunity.
