[Video] Gun Carrying Girls High School Basketball Coach Shoots 2 Armed Attackers, Saves 2 Female Players

Once again, I keep hearing the anti gunners saying that putting more good guys with guns in schools is just a recipe for more violence. I keep hearing that and we keep publishing stories to the contrary.
In this case a 70 year old Detroit girls basketball coach and 2 female players were attacked after dark in a parking lot after basketball practice by two young men armed with guns.
Fortunately, the coach has a permit to carry. He drew his own gun and shot both attackers. One died on the scene and the other was transported to an area hospital.
Both men formerly attended the high school and one was recently expelled.
I ask you, what chance would a 70 year old man and 2 high school girls have against two armed men who meant to do them harm if the coach had not been armed?
