The Houston Police Department will largely end the practice of forcibly entering homes to search them without warning, the police chief said this week, following a deadly drug raid last month that the agency conceded might have been based on faulty information.

The change, announced Monday night, came days after Chief Art Acevedo said that an officer had lied about using a confidential informant to justify searching the home. Two civilians were killed and four officers were shot during that raid, on Jan. 28.

Now, so-called no-knock warrants — a widespread but often-criticized tactic in criminal investigations — will largely be prohibited, Chief Acevedo announced at a town hall meeting on Monday. If officers want an exception to search homes without warning, they will need his express permission.

“We’ve had four officers shot, two civilians killed,” Chief Acevedo told reporters Monday. “I don’t see the value in them. So that’s probably going to go by the wayside.”
