Bill Allard confronted an armed robber in a market and shouted the command, “Police! Drop your weapon!” The gunman swung on Allard, who shot the gunman in the chest with a blast of 00 buckshot from his 14-inch-barreled Ithaca Model 37 12 gauge shotgun. The man jerked back away from him, still wielding the gun, and Allard pumped another blast of 00 buckshot through his thorax. The gunman was still up and running. Allard’s partner (an officer other than Cirillo that day) then deliberately shot the suspect in the butt with his .38 Special revolver to break his pelvis and bring him down. The .38 did exactly that, and the suspect sprawled on his face, dropping his .32 semi-auto.
Allard lowered his shotgun to a low-ready position and slowly moved in on the downed man. Suddenly, the gunman snatched up the dropped pistol and tried to roll over and bring it to bear to kill Allard, who simply pulled his own trigger and hammered a third round of buckshot into the man’s chest. The suspect dropped the gun for the last time, and the fight was over.

Can’t be too careful.
With that account, makes one wonder about the efficacy of 12 ga 00 buck...
And for every anecdote like that, there is a counter-anecdote. Plenty of stories like this where the shot man stayed put (DESPITE the victim also being shot and hobbled) and the non-shot man ran off clear.
