A Good Samaritan

In Philadelphia, a car with two female passengers stopped. A man, armed with a gun, opened a car door and attempted to rob them. An unknown armed male came to their rescue by opening fire and critically injuring the robber. He then fled the scene. It being anti-gun Philadelphia, and a flip of a coin as to the reaction he would have received for his actions from the local police, I won't argue the wisdom of his getting the hell out of Dodge. I'll just say good damn work.
