Shannon Watts believes that a good guy with a gun has never stopped a bad guy with a gun, but it looks like the events this weekend in Las Vegas have proven her wrong. After killing two police officers in a chain pizza restaurant, the murderers then made their way to a nearby Wal-Mart. Before they were able to enter the store, a citizen named Joseph Robert Wilcox, who was legally carrying a concealed handgun, confronted the murderers. From the Review Journal . . .

After the shooting, the couple headed toward a nearby Wal-Mart, where Jerad Miller was confronted by Joseph Robert Wilcox, 31, of Las Vegas. Wilcox was legally carrying a concealed pistol. Wilcox was unaware that Amanda Miller, who was pushing a shopping cart, was involved in the incident and “lying in wait,” the official said. She slipped behind Wilcox and shot him at close range. “He had no idea the wife was walking behind him,” the police official said of the murdered man. “This guy (Wilcox) was not some idiot with a gun. To me, he was a hero. He was trying to stop an active shooter.” Police said this morning that Wilcox was killed without firing a shot.

After that confrontation, the two murderers killed themselves.

Reports indicate that the two murderers had plans to move to secondary sites and continue their killing spree, but as we’ve seen time and again with active shooter situations the individuals involved immediately give up as soon as they are confronted by an armed opposition. It is tragic that Wilcox had to give his life to stop these two murderers, but there’s no doubt that his actions saved countless lives.
