Something Interesting About The Oklahoma Walmart Shooting

On Monday, a man at a Walmart parking lot in Duncan, Oklahoma shot and killed two people and then turned the gun on himself. The reports I saw only briefly mentioned how the shooting ended, reporting that "the gunman fatally shot himself after a bystander confronted him with a firearm," or something similar. However, a reader directed my attention to an article from USA Today that gives more details:

Duncan resident Aaron Helton, an Army veteran, said he was at the Walmart around 9:45 a.m. when he heard nine shots and saw the gunman, weapon in hand. According to Helton, another man walked up, put a pistol to the gunman’s head and told him to stop shooting. Helton said he saw the shooter was turning the gun on himself and looked away.

 (Underline added). While I wouldn't recommend this course of action because of the possibility of a gun disarm, it certainly brings home to the criminal that his shooting spree is, one way or another, finished.
