"....bad temper. Big woo."
Well, if the "Big woo" involves driving wrecklessly, public intoxication, and violent behavior, it is a "Big woo" indeed.
The other 2 incidents he was not shot in the back for:
Public intoxication
Driving recklessly
Violent behavior? He was using his mouth not physical contact as stated by the other officers. Resisting arrest can be non-violent also and the charges were dropped.
