Care to discuss the road rage incident that left a mother dead?

I guess some guy was acting like an ass on the road. The woman and her daughter managed to get away from him, but then the woman went home and got her 22 year old son and he got his gun, and they went looking for the guy. They found him. The guy shot the mother dead.

What in the world made her think that was a wise thing to do?

Is this possibly the result of the “I’m the nicest person in the world, but if you mess with my family I’ll become the bitch from hell” BS that keeps getting touted on Face Book, like it’s some sort of great quality for a woman to possess?
