So everytime someone violent gets to aggressive or uses their car as a weapon the police should move out the way and let them go?
You've got a car linked with a shooting in the previous days, a driver out of prison for a year with a history on a gun offence. He gets stopped,blocked in then uses the car as a weapon to ram his way out, but the police should move out the way and let him go because we don't shoot first. He was a danger to the life of the officers trying to stop him, and a potential danger to anyone on the street in any chase had he got away.
There would have been massive backlash had some innocent being knocked down as he drove away. It's nothing like what would have happened in the US either as every police there would have opened up and emptied their clip, one controlled shot that wouldn't have been aimed at his head but direct centre mass. Unfortunately it's killed him.
