A federal judge again Friday ordered agents in Chicago for immigration operations to wear and turn on their body cameras, telling them “that was not a suggestion.”

U.S. District Judge Sara Ellis issued the order Thursday, citing concerns about increasingly violent clashes between federal agents deployed in Operation Midway Blitz and the public, and their use of tear gas against protesters.

Ellis said her order requires any federal agents working under Operation Midway Blitz to wear body cameras and keep them on during all “law enforcement activities.”
