The search warrant on the apartment where Amir Locke was staying went by the rules. Minneapolis police listed the reasons they were seeking a no-knock warrant and a judge signed off on it. Police entered the dwelling with a key and once in, loudly announced their presence, as required.
And yet Locke, who was neither named in the warrant nor a suspect in the crime under investigation, was shot to death by an officer within nine seconds of police entry. He had been lying down under a blanket on a couch, his hand on a gun he had obtained legally and for which he had a permit.
It's time to change the rules.
