I thought the cops did not do too badly, considering they were confronting an armed man at close range who had just murdered a man.
Most people miss when shooting in a gunfight. These officers did better than average. From the video, it appears to me that the closest officer probably got most of the hits. He is shooting two handed, is closer, and seems more focused. The officer who is farther away is retreating and firing one handed. He does not seem as focused.
All three participants are moving. Shooting while moving is difficult.
To me, it appears to be suicide by cop.
All that and you didn’t once mention the 9 who were hit by the police. If I did that to defend myself, I would be charged with some damn crime by the DA.
