Chicago Police Supt. David Brown and Mayor Lori Lightfoot announced changes to the police department’s search warrant policy on Wednesday.

The Chicago Police Department rolled out a series of reforms on Wednesday aimed at adding guardrails around how police plan for, carry out and follow up on search warrants, more than two years after police erroneously conducted a raid on Anjanette Young’s home.

The proposed policy changes included restricting the number of police leaders who can approve search warrants. They would also require certain personnel to be on site during raids, and they chart out a process to hold officers accountable for botched warrant executions.
