"After chasing the robber into a corner of a parking lot, the robber pulled a gun on the permit holder who then drew, shot and killed the thief."
I suppose a lawyer for the deceased's family could (will?) make a case for self defense. The deceased was cornered by a stranger (we don't know if the permit holder's gun was visible or not), but he was in a corner and felt threatened. So he defended himself and was killed by this stranger who was chasing him.
Stay tuned for the court case.
