Amir Locke's death prompts ban on no-knock warrants

Amir Locke was fatally shot and killed by Minneapolis police officers executing a no-knock search warrant in February. Now, such warrants are banned in the city.

Minneapolis Mayor Jacob Frey's full ban on applying for and executing "no-knock" search warrants in the city goes into effect Friday.

The policy implementation comes just two days after the announcement that no criminal charges would be filed in the case of Amir Locke, who was fatally shot in February by Minneapolis police officers executing a no-knock search warrant on the apartment he was in.

No-knock warrants allow officers to enter a private home without knocking or making their presence known.

Frey said that exceptions could be granted for hostage situations or other extremely dangerous scenarios.
