Though it takes them a long time to admit it. (Because you just know they hate to admit it.) Deadly Wilkes-Barre Shooting Ruled Justified | WNEP.com
Seems pretty straight forward to me.
Hood had attacked a woman and was attacking the man with a knife when, in self-defense, the man shot Hood.
In fear of death or grave bodily injury, he acted to defend himself.
I would say there was a failure of the victim-selection process. Among other things.
Self-defense is a human-right.
