Don’t forget the warrant was also to arrest someone already in custody. Most witnesses say they didn’t hear a knock or identification. One cop fired for repeated hazardous behavior. Plain clothes. No body cams. Warrant supposedly “lost” for a while.
If it's a black neighborhood that means absolutely nothing, as they can be expected to lie to the police, just like the entire neighborhood in the Michael Brown case lied about what they saw the cop do. Fortunately, they lied in such stupid ways that it didn't result in the cop getting jailed. They told reporters stories like Brown was put on his knees and executed, or shot in the back, etc. What stuck was that Brown had his hands up.
Forensics showed he was shot while running forward in a tackling position, and there was blood inside the cop car from when Brown was punching the officer.
