That was a LMPD city police warrant, not an FBI warrant. FBI has much higher visibility and accountability. Due to the consequences of a potential screw up, they can't afford to be reckless. I'm 100% sure that all the whining from conservatives and trumpublicans was expected.
Bryona's home was lawfully set with a no-knock search warrant because of the alleged small time drug dealing by her BF. Both her and the BF were home during the raid. The BF contends police did not announce themselves, and and he shot through the door at whomever he thought was breaking in. (Ex BF?)
I would have done the same, but I'm not a drug dealer... So very low chance of stricking a cop on the other side. Cops returned fire by shooting blindly and irresponsibly through a window.
Thats not police procedure
