Raven Bartz argues Officer Conan Hickey shot her in the head with a
projectile fired from a less-lethal 40mm launcher while she was in a crowd of
protesters in Minneapolis after the death of George Floyd. Bartz sued Officer
Hickey and the City of Minneapolis under 42 U.S.C. § 1983 and Monell v.
Department of Social Services, 436 U.S. 658 (1978), arguing among other claims

that Officer Hickey unreasonably seized her in violation of the Fourth Amendment
of the U.S. Constitution. The district court1 granted summary judgment for the
defendants on Bartz’s Fourth Amendment claim, holding that Officer Hickey did not
violate the Fourth Amendment and was entitled to qualified immunity even if he did.
The district court declined to exercise supplemental jurisdiction over Bartz’s state
battery claim. Bartz appeals, and we affirm.
I. Background
In May 2020, protests and riots erupted in Minneapolis for several days and
nights following the death of George Floyd on May 25. Though some protested
peacefully, others burned businesses and looted stores. Officers testified that objects
such as rocks and bricks were hurled at them and fireworks and Molotov cocktails
were hurled at their precinct headquarters. On May 28, rioters stormed the police
department’s Third Precinct headquarters and set it on fire, forcing those officers
protecting it to evacuate. The Governor of Minnesota activated the Minnesota
National Guard and declared a peacetime emergency. The next day, the Governor
of Minnesota and the Mayor of Minneapolis imposed a nighttime curfew in the city,
beginning at 8:00 p.m. The Governor’s curfew order recognized that “[d]estructive
and dangerous activity” had continued since the peacetime emergency and stated the
State “must restore peace and safety immediately.” The mayoral proclamation stated
that as a result of the “civil disturbance, public safety personnel, residents, and
visitors have been and remain at risk of significant injury and death and the potential
for further civil unrest or disturbance is to such an extent that extraordinary measures
must be taken to protect the public health, safety, and welfare.” The Mayor further
explained that “much of the destruction and violence” occurred “under the cover of
darkness.”

of Minnesota.

Despite the curfew, about 2,000 individuals gathered at 9:00 p.m. outside the
police department’s Fifth Precinct headquarters for the fourth night of protests-
turned-riots. Officers gathered to protect it. As shown by the video footage of that
night submitted by the City and Officer Hickey in support of their motion for
summary judgment, which included footage of the area surrounding the police’s
Fifth Precinct headquarters, aerial surveillance of different parts of the city, and
police body camera footage, fires raged and exploded while people congregated in
the streets and moved traffic barriers. By midnight, officers had cleared some of the
area near the Fifth Precinct. As Bartz acknowledges in her brief, “[l]aw enforcement
warned protesters in the area that if they continued to ‘obstruct, resist, and/or
interfere with peace officers’” they would be arrested. As revealed by the police
body camera video footage on which she relies, around midnight police announced
to those in the area that they were in violation of unlawful assembly and were ordered
to disperse peaceably from the area immediately. Still, protestors remained in the
general area while several businesses continued to burn.
Around this time, Bartz and some friends joined protesters near the Fifth
Precinct. Bartz testified in her deposition that while they walked to their destination,
“[t]here were buildings on fire within a block.” Nevertheless, they continued
walking until they stopped in a crowd of about 100 or more people confronting a
line of police officers, including Officer Hickey of the Minneapolis Police
Department. Bartz testified they walked over halfway through the crowd until they
were about thirty to forty feet from the officers, with five rows of people in front of
them.2 Bartz testified the group she joined was protesting peacefully and that she
did not witness anyone throwing objects at officers, setting off fireworks, shining
lasers in officers’ eyes, or burning any buildings.
At 12:30 a.m., as individuals joined the crowd in front of the line of officers,
an officer threw a “blast ball” — a device that causes a loud, bright explosion and
2 Officer Hickey’s expert analyst opined the nearest protester from the officers
was 90 feet away and Bartz was approximately 132 feet away.

can contain a chemical irritant — at the crowd. After seeing the explosion, Bartz
turned to run. Around this time, Officer Hickey and another officer aimed their less-
lethal 40mm launchers toward the crowd and fired projectiles. While running, Bartz
felt a sharp hit to the back of her head. Bartz alleges it was Officer Hickey’s 40mm
projectile that hit her. She continued running for about twenty to thirty feet and then
walked before eventually sitting down. After passing out, Bartz then went to the
hospital where she received Tylenol and staples for the laceration in her head. After
running tests, hospital staff determined she did not have a concussion. But since that
night, Bartz claims she experiences headaches, emotional distress, and memory loss.
Bartz sued Officer Hickey and the City of Minneapolis, asserting a Fourth
Amendment excessive force claim, a Monell claim, and a state law battery claim.3
The district court granted the defendants’ summary judgment motion on the federal
claims against Officer Hickey, determining he did not seize Bartz for purposes of
the Fourth Amendment and that he was entitled to qualified immunity even if he did
seize her. The district court also held the Monell claim against the City failed
without an underlying constitutional violation, and it declined to exercise
supplemental jurisdiction over the remaining state law claim. Bartz now appeals
arguing (1) Officer Hickey violated her clearly established Fourth Amendment right
against unreasonable seizure; (2) the City is liable under Monell; and (3) the
defendants are not entitled to summary judgment on her state law battery claim.
II. Analysis
We review de novo a district court’s grant of summary judgment based on
qualified immunity. De Mian v. City of St. Louis, 86 F.4th 1179, 1182 (8th Cir.
2023). “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.’” Id. (quoting Fed. R. Civ. P. 56(a)). Though we view the facts most

Hickey and the City, but the parties stipulated to their dismissal.

favorably to Bartz, “we may rely on video evidence found in the record where that
video evidence ‘blatantly contradicts’ the nonmoving party’s characterization of the
facts.” Brown v. City of St. Louis, 40 F.4th 895, 899 (8th Cir. 2022) (brackets
omitted) (quoting Steed ex rel. Steed v. Mo. State Highway Patrol, 2 F.4th 767, 770
(8th Cir. 2021)). And we “may affirm the grant of summary judgment ‘on any
ground supported by the record.’” Pollreis v. Marzolf, 66 F.4th 726, 729 (8th Cir.
2023) (quoting Adam & Eve Jonesboro, LLC v. Perrin, 933 F.3d 951, 958 (8th Cir.
2019)), cert. denied, 144 S. Ct. 2580 (2024).
To overcome qualified immunity, Bartz “must show that the officer[] violated
a constitutional right, and that the unlawfulness of [his] conduct was clearly
established at the time.” Dundon v. Kirchmeier, 85 F.4th 1250, 1255 (8th Cir. 2023).
“For a right to be clearly established, the ‘contours of the right must be sufficiently
clear that a reasonable official would understand that what he is doing violates that
right.’” Id. (quoting Anderson v. Creighton, 483 U.S. 635, 640 (1987)).
Bartz argues Officer Hickey violated her Fourth Amendment rights. The
Fourth Amendment protects “[t]he right of the people to be secure in their persons,
houses, papers, and effects, against unreasonable searches and seizures . . . .” U.S.
Const. amend. IV. This right includes protection against unreasonable seizures
involving the use of excessive force. See Graham v. Connor, 490 U.S. 386, 395
(1989); Burbridge v. City of St. Louis, 2 F.4th 774, 780 (8th Cir. 2021). To establish
an excessive force claim under the Fourth Amendment, “the claimant must
demonstrate a seizure occurred and the seizure was unreasonable.” McCoy v. City
of Monticello, 342 F.3d 842, 846–47 (8th Cir. 2003). We assume, without deciding,
that a seizure occurred here, and we resolve this case by answering whether Officer
Hickey’s use of force was reasonable.
We evaluate the use of force based on an objective reasonableness standard,
undertaking “a fact-intensive inquiry.” McDaniel v. Neal, 44 F.4th 1085, 1090–91
(8th Cir. 2022). The officer’s use of force is “judged from the perspective of a
reasonable officer on the scene,” considering “the facts and circumstances of each

-- 5 of 12 --

particular case, including 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.” Pollreis v. Marzolf, 9 F.4th
737, 747 (8th Cir. 2021) (quoting Graham, 490 U.S. at 396). In our evaluation, we
balance “the nature and quality of the intrusion on the individual’s Fourth
Amendment interests against the countervailing governmental interests at stake.”
Burbridge, 2 F.4th at 780 (quoting White v. Jackson, 865 F.3d 1064, 1074 (8th Cir.
2017)). And we are mindful that “[t]he calculus of reasonableness must embody
allowance for the fact that police officers are often forced to make split-second
judgments—in circumstances that are tense, uncertain, and rapidly evolving—about
the amount of force that is necessary in a particular situation.” Graham, 490 U.S. at
396–97.
It is true “we have held time and again that, if a person is not suspected of a
serious crime, is not threatening anyone, and is neither fleeing nor resisting arrest,
then it is unreasonable for an officer to use more than de minimis force against him.”
Mitchell v. Kirchmeier, 28 F.4th 888, 898 (8th Cir. 2022). But our balancing of an
individual’s Fourth Amendment interests and the countervailing governmental
interests at stake does not take place in a vacuum.
As the Supreme Court recently reiterated, our “inquiry into the reasonableness
of police force requires analyzing the ‘totality of the circumstances.’” Barnes v.
Felix, 145 S. Ct. 1353, 1358 (2025) (quoting County of Los Angeles v. Mendez, 581
U.S. 420, 427–28 (2017); Tennessee v. Garner, 471 U.S. 1, 9 (1985)). “[T]he
situation at the precise time of the shooting will often be what matters most,” but
“earlier facts and circumstances may bear on how a reasonable officer would have
understood and responded to later ones.” Id. “The history of the interaction, as well
as other past circumstances known to the officer, thus may inform the reasonableness
of the use of force.” Id. Relevant factors we may consider include “the relationship
between the need for the use of force and the amount of force used; the extent of the
plaintiff’s injury; . . . the severity of the security problem at issue; the threat
reasonably perceived by the officer; and whether the plaintiff was actively resisting.”

Kingsley v. Hendrickson, 576 U.S. 389, 397 (2015). Here, although some of the
protesters were protesting peacefully, the situation confronting Officer Hickey was
a far cry from “a peaceful scene interrupted by rubber bullets and tear-gas.” Quraishi
v. St. Charles County, 986 F.3d 831, 836 (8th Cir. 2021) (concluding an officer did
not have arguable probable cause to use tear-gas based on a belief that those
reporting on a protest were committing crimes).
Bartz and other protesters were defying a citywide curfew during a declared
peacetime emergency while parts of the city burned and rioters caused violence and
destruction. Viewing the video footage in the record of that night, the circumstances
resemble a war-torn city more than a peaceful protest. See Brown, 40 F.4th at 897,
902–03 (relying on video evidence submitted by officers in support of their motion
for summary judgment depicting the circumstances at issue). Just the night before,
rioters overtook and burned down the police department’s Third Precinct, which
Officer Hickey protected until the officers’ emergency evacuation. See Barnes, 145
S. Ct. at 1358 (explaining that “earlier facts and circumstances may bear on how a
reasonable officer would have understood and responded to later ones”). As
explained by the curfew announcement issued by the Governor, “[d]estructive and
dangerous activity” had continued since the declaration of a peacetime emergency
and the State needed to “restore peace and safety immediately.” And as the Mayor’s
curfew announcement stated, “public safety personnel, residents, and visitors” were
“at risk of significant injury and death and the potential for further civil unrest or
disturbance” was so likely that “extraordinary measures” needed to be taken “to
protect the public health, safety, and welfare.” From the perspective of a reasonable
officer on the ground, this night was taking shape like the night before. The
circumstances revealed the “severity of the security problem at issue” and the “threat
reasonably perceived by the officer.” Kingsley, 576 U.S. at 397. And yet Bartz
violated curfew and ventured into the turmoil while police sought to protect the city
and the public. Even if well-intentioned, during this chaos, Bartz and the other
protesters posed a threat to the officers and the public safety. Graham, 490 U.S. at
396 (explaining the test of reasonableness requires “careful attention to the
. . . immediate threat to the safety of the officers or others”).

Nevertheless, Bartz argues that firing a round from a 40mm launcher at the
head of a person constitutes use of deadly force. As support, she primarily relies on
Marks v. Bauer, 107 F.4th 840 (8th Cir. 2024), vacated, 1145 S. Ct. 2733 (2025)
(mem.), remanded to, 166 F.4th 1121 (8th Cir. 2026).4 Marks is distinguishable
from the situation here. Unlike the officer in Marks, Officer Hickey’s 40mm
projectile did not hit a protester “in the face from approximately five to ten feet
away.” Marks, 166 F.4th at 1121 (footnote omitted). And in Marks, the projectile
hit the protester in the eye, “rupturing his right eyeball, fracturing his eye socket,”
“causing a traumatic brain injury,” and making the protester “legally blind in that
eye.” Id. at 1126. Though Bartz testified the projectile that hit her caused symptoms
after the incident (such as losing consciousness, seizing, headaches, emotional
distress, and memory loss), Bartz was able to run and walk away from the protest
just after the use of force, hospital staff later determined she did not have a
concussion, and she received staples and Tylenol at the hospital. Thus, her injuries
are also less severe than those in Marks. See Kingsley, 576 U.S. at 397 (noting the
court may consider “the extent of the plaintiff’s injury” when determining the
reasonableness of the use of force).
Ultimately, under “circumstances that [were] tense, uncertain, and rapidly
evolving,” the government had a strong interest in using force to bring the situation
under control. See Graham, 490 U.S. at 397. “Where law enforcement was trying
to control a rapidly escalating situation, we have held that the use of force was not
unreasonable.” Jackson v. Stair, 944 F.3d 704, 711 (8th Cir. 2019). The video
footage in the record reveals the intensity of the situation Officer Hickey faced that
night protecting the Fifth Precinct. See Brown, 40 F.4th at 897, 902–03 (relying on
video evidence submitted by officers in support of their motion for summary
judgment depicting the circumstances at issue). Given the chaotic and threatening
4 The Supreme Court vacated and remanded our decision in Marks I “for
further consideration in light of” its recent opinion, Barnes v. Felix, 605 U.S. 73
(2025). Marks, 145 S. Ct. 2733. On remand in Marks II, we applied Barnes’s
“moment-of-threat” rule, but this did not impact our analysis as to whether the
officer’s use of force was deadly. See 166 F.4th at 1125, 1129.

conditions unfolding after nights of protests-turned-into-riots, including the threat to
police headquarters, first responders, and the public, a reasonable officer could
conclude those defying the curfew and confronting the officers that night presented
a serious threat that needed to be brought under control. We therefore conclude
Officer Hickey’s firing of a 40mm projectile was reasonable. See White, 865 F.3d
at 1079 (concluding officer’s use of non-lethal projectiles was reasonable when the
officer “could have concluded that [the plaintiff] had been a part of the violent
crowd, that his advances toward the skirmish line posed a threat to officer safety,
and that he disobeyed officer orders to stop”). Officer Hickey is thus entitled to
summary judgment.
Having determined Bartz’s excessive force claim under the Fourth
Amendment fails, we turn to her Monell and state law claims. She argues the
Minneapolis Police Department had a widespread custom of using unreasonable
force and that this alleged custom caused the violation of Bartz’s constitutional
rights. But as explained, Officer Hickey’s conduct did not violate the Constitution,
so Bartz’s Monell claim must fail absent an underlying constitutional violation. See
Whitworth v. Kling, 90 F.4th 1215, 1218 (8th Cir. 2024). As to her state law battery
claim, she argues the City and Officer Hickey are not entitled to summary judgment.
But the district court declined to exercise its supplemental jurisdiction over this
claim, and Bartz does not argue it abused its discretion by doing so. Thus, we will
not disturb the district court’s decision to decline exercising jurisdiction. See De
Mian, 86 F.4th at 1183.
III. Conclusion
For the foregoing reasons, we affirm.
KELLY, Circuit Judge, dissenting.
I would conclude that a reasonable jury could find Bartz was seized for
purposes of the Fourth Amendment when she was hit with a 40mm projectile.

Because the district court found Bartz was not seized and did not reach the question
of whether the force used against her was reasonable, I would remand to the district
court for further analysis rather than address that question in the first instance. For
this reason, I respectfully dissent.
In an excessive force claim, the “threshold question” is whether a seizure
occurred. Dundon v. Kirchmeier, 85 F.4th 1250, 1255 (8th Cir. 2023). As the
Supreme Court has explained, “a seizure requires the use of force with intent to
restrain.” Torres v. Madrid, 592 U.S. 306, 317 (2021) (citation modified). And “the
application of physical force to the body of a person with intent to restrain is a seizure
even if the person does not submit and is not subdued.” Id. at 325. In determining
whether there was an intent to restrain, neither accidental force nor “force
intentionally applied for some other purpose” will qualify; the “appropriate inquiry
is whether the challenged conduct objectively manifests an intent to restrain[.]” Id.
at 317. In line with this guidance, we “have recognized a potential distinction
between force used with intent to apprehend and force used with intent to disperse
or repel.” Dundon, 85 F.4th at 1256; see also Keup v. Sarpy County, 159 F.4th 533,
538–39 (8th Cir. 2025) (stating that “what matters is whether the record
demonstrates that the officer applied force to restrain or to disperse” before holding
that an officer did not objectively manifest an intent to restrain because the officer
“fired to disperse, not to seize” (citations modified)).
Viewing the evidence in the light most favorable to Bartz, a reasonable jury
could find that she was seized. Bartz presented evidence that munitions of the kind
Officer Hickey employed here are designed and used to incapacitate, not to disperse.
Minneapolis Police Department (MPD) policy states that “Officers shall not deploy
40mm launchers for crowd management purposes.” MPD policy further defines
40mm less-lethal rounds as “[d]irect fire round[s] used in situations where maximum
deliverable energy is desired for [] incapacitation[,]” (emphasis added), and
accordingly allows them to be deployed when “incapacitation . . . is desired.”
(emphasis added). In sum, as a matter of MPD policy, 40mm less-lethal rounds are

-- 10 of 12 --

-11-
prohibited for the purpose of dispersal and may only be used when an officer intends
to incapacitate.
The particular circumstances under which Hickey fired the 40mm round at
Bartz also suggest Hickey did not use the force to disperse. The record shows that,
at some point during the protest, an officer threw a blast ball—an action that no one
seems to dispute was an attempt at dispersal. In response to the blast ball, many
people—including Bartz—turned to run. A couple seconds later, Hickey fired his
40mm launcher, striking Bartz in the back of the head. When he shot her, Bartz was
already running away. She was not moving toward him or the line of officers nor did
she remain in place. A reasonable jury could find that Hickey’s use of his 40mm
launcher, after the use of a blast ball intended for dispersal, was intended to
incapacitate her.
And “the amount of force remains pertinent in assessing the objective intent
to restrain.” Torres, 592 U.S. at 317. A lesser amount of force, such as “[a] tap on
the shoulder[,] . . . will rarely exhibit” an objective intent to restrain. Id. Conversely,
as the amount of force increases, so does the likelihood that an officer objectively
intended to restrain. “The degree of injury [a plaintiff suffered] is certainly relevant
insofar as it tends to show the amount and type of force used.” Chambers v.
Pennycook, 641 F.3d 898, 906 (8th Cir. 2011) (citations omitted). And “[w]e think
it enough for a seizure that a person be stopped by the very instrumentality set in
motion or put in place in order to achieve that result.” Brower v. County of Inyo,
489 U.S. 593, 599 (1989)). After being struck in the head by the projectile, Bartz
lost consciousness, had a seizure, and required hospital care. At that point, Bartz was
actually stopped. Moreover, MPD policy addresses “Target Areas” when using
40mm launchers:
Officers shall be aware that the delivery of the 40mm impact projectiles
to certain parts of the human body can cause grievous injury . . . or
possible death. Areas susceptible to death or possible severe injury are
the head, neck, throat and chest . . . . Unless deadly force is justified,

-- 11 of 12 --

-12-
officers should avoid the delivery of 40mm impact projectiles to any of
the above-described areas.
As the district court found, a reasonable juror could conclude that it was Hickey who
struck Bartz, and it is undisputed that Bartz was struck in the head. Hickey testified
that he did not believe he struck any unintended person with 40mm munition that
night. And he could recall only one instance in which he struck a person on an
unintended part of their body—and that person was not Bartz. Together with the
MPD policy, this evidence would allow a reasonable jury to find that Hickey used
an amount of force that objectively reflects an intent to restrain.5
This evidence as a whole, and viewed in the light most favorable to Bartz,
would permit a reasonable juror to find that Hickey had an objective intent to restrain
when he fired 40mm munition at Bartz’s head. I would remand to the district court
for further proceedings.
______________________________
5 The record also includes evidence that officers at the protest planned to make
mass arrests. Bartz submitted officer statements made after the fact that indicated
there had been a plan to “try to make a mass arrest” of “all the protesters” in the
same area where Bartz was protesting. She also relied on the City of Minneapolis’s
official position on the very protest she participated in: “SWAT officers were asked
not to make arrests and leave that to the strike teams and some of the mobile field
officers.” Hickey was a member of the strike team that night. While the officers’
subjective intent is not at issue, “[i]ntent matters . . . to the extent it ‘has been
conveyed’ to others.” Hight v. Williams, 164 F.4th 672, 675–76 (8th Cir. 2026)
(quoting Irish v. McNamara, 108 F.4th 715, 719 (8th Cir. 2024)).
