I bet you believe in Santa Claus too.
Sure Sure, FEEB agent shoots guy in face with M-16 - no consequences. Swat goon murders 12 year old - shoots him in the back with a shotgun while the 12 year old is lying on the floor - no consequences. Cop kills guy in costume at Halloween party by shooting him through the window - no consequences. Just a few examples of a great many unpunished crimes. Show me some examples where cops have been criminally prosecuted for killing somone when they were on duty in the last couple of years. You can't because there aren't any.
