Police tried to detain Blair so that he wouldn't be in the house when it was raided, but pulled over the wrong person. Despite that mistake, and despite the knowledge that the roommate had moved out, the raid on Blair was still carried out. It was hastily planned, reported the Tribune, diverting from protocol. Burnett, who shot Blair, told investigators that it is "absolutely not our standard" to carry out such a raid with as little planning as was done, according to the Tribune.
It was so hastily carried out, in fact, that police forgot the warrant. According to the Tribune, in the video it obtained an officer can be heard asking: "Did somebody grab a copy of the warrant off my desk?"
Burnett replies: "Oh, don't tell me that." He then complains to the other officers: "He doesn't have a copy of the warrant."
Minutes later, Blair would be dead.
