A Phoenix police sergeant has been placed on administrative leave after showing up armed and masked to a student-led protest against ICE at a high school in Chandler, Arizona. Sergeant Dusten Mullen told fellow officers he attended the peaceful protest with the intent of provoking the students into breaking the law so they could be arrested.

Why it matters

The incident has sparked outrage in the community, with concerns that a police officer would try to undermine a lawful student protest by acting as an agent provocateur. It raises questions about the appropriate conduct of law enforcement, even when off-duty, and the need to hold officers to a higher standard of behavior.

The details

According to a police report, Mullen told Chandler police officers on the scene that his "plan is legitimately to just let them all assault me and you guys arrest them all and I'll keep it on film." Mullen, who in 2025 drew a salary of $336,518, was suspended with pay and required to surrender his badge and gun pending an internal investigation.

  • The protest at Hamilton High School took place on January 30, 2026.
  • Mullen was placed on administrative leave following the incident.

What they’re saying

“As law enforcement professionals, we are held to higher standards of conduct — both in and out of uniform. 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.”

— Matthew Giordano, Phoenix Police Chief

“Placing Sgt. Mullen on administrative leave and issuing a media advisory that suggests misconduct based solely on his lawful, off-duty expressive activity appears to chill the exercise of constitutionally protected speech and risks violating both federal and state constitutional guarantees.”

— Steve Serbalik, Attorney representing Sergeant Mullen

“We had no idea why he was there, he's wearing a mask, and even if he did not plan to use his gun, we still don't know what's going to happen, right? We had all just witnessed the shooting of Alex Pretti, where he was at a protest with a gun and he ended up getting shot and killed. And so even if this armed person did not touch his gun, we still don't know what's going to happen.”

— Megan Craghead, Mother of protest attendee

What’s next

The judge will decide on Tuesday whether to allow Sergeant Mullen to be released on bail pending the outcome of the internal investigation.

The takeaway

This incident highlights the need for greater accountability and oversight of law enforcement, even when officers are off-duty. It raises concerns about the appropriate use of force and the potential for abuse of power, especially in the context of peaceful protests. The community is rightfully demanding that officers be held to the highest standards of conduct to maintain public trust.
