It is certainly insufficient to be a CCW if the Perp is already Danger Close. Who knew that provoking the simple mind would lead to death? Mental illness cannot be measured in a man's (or boy's) eyes unless the afflicted one has a Tell. By the time the realization was in the Victim's Mind's Eye, he was stabbed and dying. Too soon. Too fast. Too stupid.
How does the World put up with this? How does the murdered Victim become the Aggressor and vice versa? Who ARE the people in that " Go Fund Me" neighborhood? It is Bizzare World in the extreme.
