ORDER AND JUDGMENT * _________________________________

Before McHUGH, CARSON, and ROSSMAN, Circuit Judges. _________________________________

Plaintiff Michael Driscoll protested in the streets of Denver following George

Floyd’s death. A projectile hit Plaintiff’s head and injured him. He sued the City

and County of Denver. The problem for Plaintiff is that officers from Jefferson

County, Colorado were at the scene that evening. And Plaintiff did not provide the

district court with evidence to show a Denver police officer, rather than a Jefferson

County officer, fired the projectile.

* This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel. It may be cited, however, for its persuasive value consistent with Fed. R. App. P. 32.1 and 10th Cir. R. 32.1. Appellate Case: 25-1139 Document: 85 Date Filed: 07/31/2026 Page: 2

With no evidence as to who fired the projectile, the district court entered

summary judgment against Plaintiff. In the district court’s view, allowing the case to

move forward would require a jury to rely on mere speculation. We agree with the

district court that Plaintiff presented insufficient evidence to survive summary

judgment on this portion of his complaint. But Plaintiff also alleged the City and

County of Denver violated his constitutional rights in other altercations earlier the

same evening. The district court, however, failed to address the additional alleged

instances of constitutional violations by Denver but still granted summary judgment

on all claims. The district court must address these alleged violations in the first

instance. We exercise jurisdiction under 28 U.S.C. § 1291 and affirm in part, reverse

in part, and remand for further proceedings.

I.

Following the death of George Floyd, Denver faced unprecedented protests.

The Denver Police Department made and executed an operations plan for each

protest day from May 28, 2020, to June 2, 2020. On May 30, the City of Denver

imposed a curfew on all public places from 8:00 p.m. until 5:00 a.m. The May 31,

2020, plan stated that law enforcement would respond in accordance with Denver’s

crowd management manual and that any officer deploying chemical agents or using

force during the events would adhere to normal use of force reporting requirements.

Due to the sheer volume of protests and protestors, other law enforcement

agencies assisted the Denver Police Department in responding to the protests. The

Jefferson County Regional Special Weapons and Tactics Team (“Jefferson County

2 Appellate Case: 25-1139 Document: 85 Date Filed: 07/31/2026 Page: 3

SWAT”) was one such partnering agency on May 31, 2020. The Denver Police

Department assigned Jefferson County SWAT to respond to locations needing a law

enforcement presence as an immediate reaction team. Outside agencies such as

Jefferson County SWAT used their own standard protocols and made their own

decisions about use of force.

Plaintiff drove to Denver to participate in the protests on May 30 and 31, 2020,

wearing a gas mask and carrying a wooden shield with the inscription “ACAB.” On

May 30, Plaintiff participated in a large protest at Colfax Avenue and Lincoln Street

in Denver (“Colfax and Lincoln Event”), where he alleges a Denver Police

Department officer, without provocation, threw a tear gas canister at him and caused

him pain.

On May 31, Plaintiff was present when law enforcement advised protestors of

the 8:00 p.m. curfew. At about 8:40 p.m., Plaintiff was at the intersection of Colfax

and Clarkson when law enforcement ordered the crowd to disperse in compliance

with the curfew. Protestors threw water bottles at law enforcement, some containing

urine. Law enforcement officers from Brighton and Commerce City responded to the

protestors at this location. Plaintiff presented no evidence of Denver Police

Department officers using force at Colfax and Clarkson when he was there that

evening.

By 9:09 p.m., Plaintiff had migrated to a position on Colfax Avenue between

Washington and Clarkson streets (“Colfax and Clarkson Event”). Law enforcement

announced dispersal orders over loudspeakers. Someone threw at least one glass

3 Appellate Case: 25-1139 Document: 85 Date Filed: 07/31/2026 Page: 4

bottle at the police line. Plaintiff kicked an object—he claims to get it out of his

way. This alerted law enforcement to Plaintiff. Defendant Hyatt deployed an “OC

blast” in Plaintiff’s direction and Defendant Cochran fired a 40mm foam round in

Plaintiff’s direction. Plaintiff retreated.

At around 10:00 p.m., Plaintiff made his way to 13th and Cherokee—the area

near Denver Police Department headquarters (“13th and Cherokee Event”). Plaintiff

joined around 100 people. Defendant Phelan directed Jefferson County SWAT to

respond to the area. Jefferson County SWAT formed a skirmish line down the street

from the crowd. Jefferson County SWAT deployed less-lethal platforms at around

10:10 p.m. 1 One protestor threw a canister back at law enforcement. An object struck

Plaintiff in the head. Plaintiff did not see who deployed the projectile.

Plaintiff filed suit, bringing six claims against the City and County of Denver

and various other Denver employees—Fourth Amendment excessive force,

Fourteenth Amendment excessive force, First Amendment free speech and assembly,

First Amendment retaliation, Fourteenth Amendment procedural due process, and

municipal liability failure to train. He amended his complaint twice. After Plaintiff

voluntarily dismissed his claims against four of the individual Defendants, the district

court dismissed the claims against the remaining individual Defendants. Plaintiff

does not challenge those dismissals on appeal. The district court also dismissed

Plaintiff’s failure to train claim against Denver, which Plaintiff does not appeal.

1 Denver utilized “less-lethal platforms” in response to the protests. These included 40mm and PepperBall systems and CS canisters containing tear gas. 4 Appellate Case: 25-1139 Document: 85 Date Filed: 07/31/2026 Page: 5

Denver then moved for summary judgment. The district court granted Denver’s

motion, determining that (1) Plaintiff did not provide sufficient evidence for a

reasonable jury to conclude that a Denver employee violated Plaintiff’s constitutional

rights, and (2) that Plaintiff did not demonstrate that Denver could be held liable for

the actions of a nonemployee—Jefferson County SWAT—acting as Denver’s agent.
