Good Samaritan saves Arizona Trooper

Arizona trooper shot in ambush attack; Good Samaritan kills gunman

The Good Samaritan came up int eh incident while the assailant and trooper were struggling on the ground. The Good Samaritan ordered the assailant to stop and when he didn't went to his car, got his gun, and shot the bad guy. I think there is little doubt he saved the Trooper's life. Lucky there was a good man with a gun available to help.
