Dusten Mullen, a sergeant with the Phoenix Police Department, has been placed on administrative abandon after admitting he attended a student-led immigration protest with the specific goal of inciting an altercation. The incident, which occurred on January 30 at Hamilton High School in Chandler, Arizona, has raised serious questions about professional conduct and the use of police tactics against minors.
According to official reports, the armed off-duty cop tried to incite violence at high school ICE protest by acting as an agent provocateur. Mullen told responding officers on the scene that his intention was to provoke the students into a physical confrontation that would justify their arrest.
“My plan is legitimately to just let them all assault me and you guys arrest them all and I’ll keep it on film,” Mullen said, according to a police report. He further noted that he had other individuals filming the encounter from a distance.
Phoenix Police Chief Matthew Giordano confirmed that Mullen has been suspended with pay pending an internal review. As part of the disciplinary action, Mullen was required to surrender his badge and service weapon. “As law enforcement professionals, we are held to higher standards of conduct — both in and out of uniform,” Giordano said. “When we fall short, we must be accountable, and we will not tolerate actions which undermine the trust the community has placed in the Department.”
A Scene of Escalation and Fear
The protest at Hamilton High School was part of a wave of student-led walkouts across the Phoenix area. These demonstrations followed the killing of Alex Pretti by Customs and Border Protection officers in Minneapolis, leading hundreds of students to rally against U.S. Immigration and Customs Enforcement (ICE).
Witnesses described a peaceful atmosphere that shifted abruptly when Mullen arrived. Megan Craghead, a parent at the school, recalled that the event was upbeat until reports surfaced of an armed man confronting the students. She described seeing a man walking the sidewalk, acting smugly and yelling at the teenagers, which she feared could easily escalate into a traumatic event.
Visual evidence from the scene shows Mullen wearing a T-shirt featuring an American flag and the phrases “Trump 2024” and “We took the country back.” To conceal his identity, he wore a neck gaiter over his face. He was also armed with a handgun and several spare magazines visible on his hip.
During the encounter, Mullen claimed to the Chandler Police Department that he had been assaulted while recording the students on his cellphone. Still, bystanders captured on film disputed this, with one individual shouting, “Grown-ass man, out here with a gun crying about a little kid.”
Legal Fallout and the Arrest of a Minor
The confrontation led to the immediate arrest of a teenage girl. The Chandler Police Department initially reported that she had thrown a water bottle at Mullen. However, video footage later suggested that only water—and no bottle—hit the sergeant. Following a review of the evidence, the Maricopa County Attorney’s Office dropped all charges against the girl.
Mullen’s legal representation has pushed back against the department’s disciplinary measures. Steve Serbalik, an attorney for Mullen, argued that his client was exercising his constitutional right to voice disagreement as a private citizen.
In a letter to Chief Giordano, Serbalik stated that placing Mullen on leave based on “lawful, off-duty expressive activity” risks violating federal and state constitutional guarantees and may chill protected speech. He urged the department to lift the administrative leave and withdraw the media advisory regarding the misconduct.
Institutional Context and Community Outrage
The incident has reignited criticism of the Phoenix Police Department’s culture. Bill Moore, a Phoenix-based defense attorney, noted that the department has a history of failing to hold personnel accountable—a pattern that contributed to a civil-rights probe by the U.S. Department of Justice in 2024.
Moore suggested that the decision to suspend Mullen indicates the severity of the internal findings. “The ‘blue line’ thing is still very much a thing here,” Moore said, referring to the unwritten code where officers protect one another from misconduct complaints. “That they took this action tells me that their internal investigation must be fairly damning.”
Community leaders have also expressed alarm over the presence of a weapon at a youth-led event. Brandy Reese, a co-leader of a local Indivisible chapter, questioned why an off-duty officer felt the need to be armed while confronting children. For parents like Craghead, the issue is one of professional ethics; she argued that while a private citizen might have the right to counter-protest armed, a public safety officer should be held to a higher standard, especially when the intent is to agitate minors into breaking the law.

The department is expected to release a final determination once the review of the evidence and the sergeant’s conduct is complete.
