Anything being that Saint Mike was WILLING to take the cops gun away from him. He had JUST tried after attacking and assaulting the cop BEFORE the cop got out of his vehicle.
If the cop was still afraid for his life then get in the SUV, roll-up the window, and lock the door, and call in the report to dispatch, and wait for back-up.
I don't know the cops state of mind. But likely he was concerned for the public. A large man had just violently attacked him, tried to get his gun and was now trying to escape into the general public. That's not the behavior of a sane, civilized, rational person. We KNOW that Saint Mike had JUST robbed a store and assaulted the owner. The cop either didn't know that or DID know that...either way it would have been a dereliction of duty to let the guy get away. And when Saint Mike doubled down and came at the cop when the cop DID get out of the car, then Saint Mike was finished.
So out of concern for the public he fires off atleast 8 rounds -- some of which miss and hit the residences around there on a Saturday afternoon where kids are outside playing.
