I haven't commented on this yet for a reason. In fact, anyone that has commented and drawn conclusions before learning anything, is looking for what they want to see and immediately assumed cops were in the wrong.
I could never be a cop and deal with the dangers they do. There are some really bad ones for sure and I've seen way more abuse of power, racism and murder than I ever care to.
But if I'm a cop in that situation, and some arrogant idiot is telling me to F off and don't tap on my window (after I rightfully pulled him over), then refuses to open window, a dark tinted window, I am doing the same damn thing. Hauling his ass out of there and cuff him. Then when he is flapping his yap and lying about he was about to come out (bullshit) as I am telling him to get down on his knees, if he isn't doing it, I am forcing his sorry ass down.
