Because of what that cop chose to do, nothing else dangerous took place, like that car being used any further as a life ending weapon for example which is the reason why cops are out there in the first place. They do what they can to put a stop to what is labeled illegal activity and should someone end up getting killed in the process, you only have the lawbreakers to blame for it because of their decision to instigate whatever happens next. You as well be saying that a lady doesn't have the right to defend herself whenever a man starts beating on her.
God bless you always!!!

P.S. The best way for evil to triumph is for a good person to stand there and not do a thing.
