No as I said forget the Hockey players, The hockey players are irrelevant to this. I'm talking about the college students that ran off and left the guy fighting for his life alone. None of them went to his aid.
You may not know what you would do, but I definitely know what I would do. Running would not be an option. I've been in similar situations before, I took the gun away from the attacker. Wanted to shoot him, but was too busy beating him senseless with his own gun. I'm not a violent person, I just believe the best defense is a stronger offense. Someone attacks me I'm going on the offense. When the guy shoved a gun in my face in DC and yelled, "Pullover mothXXXXXXXX or I'm going to blow your head off". I crushed him between the door of my truck and the top of the car he was hanging out of. Yea he shot at me, but I was holding of his wrist, and controlling the gun. Still got that gun. Cheap Hi Point 45 auto. Shoots well, just heavy.
My son has already proven what he will do in a situation like this. He saw a friend attacked by a guy with a knife one night. He tackled the attacker, then broke the attackers arm when he tried to stab him. My son was too late to save his friend, he died on the way to the hospital. My son was just a Sophomore in high school at the time.
