From what I've read, there is some question whether the police announced themselves or not. The police claim they did, and have at least one corroborating witness. The boyfriend who fired shots claims he didn't hear the announcement and other neighbors didn't hear the announcement. I will say it's probable that they did announce, but, for whatever reason (maybe asleep until they broke down the door) he didn't hear it. While I can't say that the officers on the raid were wrong to return fire, I do have to question the necessity of doing a middle of the night no-knock search in the first place. Although I won't say that such tactics are never justified, IMO, they are way over-used, and are extremely dangerous to both law enforcement and citizens. A middle of the night no-knock raid should be near the bottom of the list of options, and shouldn't be conducted on the basis of a wild guess, based on past associations, the a certain person might be there.
