I think the the morons that train these cops full them full of fear about "You've got to shoot first so you go home safe!", and so overtrain the cops to shoot, and in this case shoot an innocent civilian complying with police.
Had there not been a video, the "police trainers" also tell the cop exactly what to say: "I was in fear for my life".
The other day a LEO trainer called into Rush and said he teaches that action always beats reaction, ie, shoot first and ask questions later.
I guess they save the tasers for little old ladies and protesters;
Well, they id a shi**y job training this guy. 4 shots at close range with only one hit in the groin. My wife, who rarely shoots, would have done a lot better. At 15 yards with my Sig Sauer 40 I can put 6 in the size of a silver dollar. Of course the silver dollar is not shooting back.
