Greg Stutzman is a hero. Seems like nobody else really wanted to get involved until they were sure that he had the perp completely subdued.    In retrospect, since Greg had him on the ground with the back of his legs exposed it's a real shame that nobody had the presence of mind to slice the groids Achilles tendon. (perhaps I wouldn't of either, but I'm sure I would have helped) They could have let him loose and he would not be able to get too far. :D
