It was someone that was speeding, now I can understand if it was a high speed chase or something. I can even understand pulling the gun out. I cannot understand tugging on the woman to get her out of the car when she is trying to explain herself and is showing NO Hostile movements/actions.
He lost his cool in a very bad way, he let himself get out of control. Who is to say next time he went out of control his trigger finger didn't get itchy and shoot the person? He deserved to be fired, a 6 figure settlement is too much for this, 10k at the most. But oh well.
