AI Summary

Dusten Mullen, a sergeant with the Phoenix Police Department, has been placed on administrative leave after showing up armed and off-duty to a student-led anti-ICE protest at Hamilton High School in Chandler, Arizona, on January 30. Mullen, who earned $336,518 in 2025, told fellow police officers he intended to act as an agent provocateur to incite students. Phoenix Police Chief Matthew Giordano stated Mullen's conduct undermined community trust and that the department would hold him accountable.
