Wow. That old girl has presence of mind. Not only was she able to get to her weapon and use it, she even got the license plate number. Most impressive.
I agree.
I hope that the local prosecutor isn’t a jerk, because she could be prosecuted. Once the attacker is running away, you’re supposed to stand down under most circumstances, not shoot repeatedly at the tailgate of their car - according to the deadly force laws in every state I know of.
Deadly force is justified when you are in reasonable immediate fear of great bodily harm or death. Once you see the tail lights speeding away from you, “reasonable fear” would be a hard sell.
