A good guy with a gun...stops a bad guy with a gun.Arizona trooper stops to help a victim in a rollover MVA, and is ambushed by a random motorist who shoots the trooper in the chest, then wrestles him to the ground. A good Samaritan comes to help the trooper, but the attacker refuses to stop attacking the trooper. Good Samaritan returns to his vehicle and retrieves a firearm, shooting the ****** dead right there. Trooper is in stable condition. I'd say this guy is a bona fide hero. abc7.com/news/az-tro oper-shot-in-ambush- attack;-good-samarit an-kills-gunman
