the robber was running.. Dude might have been giving chase. Again how does ANYONE know the guy chasing the robber is telling the truth?
Again I am glad they caught the bad guy, but, what if the guy chasing the other was really the bad guy and they shot the wrong person?
Probably why Police give up the chase after losing sight of their suspect - yeah? Who knows, just another innocent running guy trying to lose some excess weight.
Not being sarcastic but I've found that life is full of what if's.
