I love this one, thanks to the Gunslinger's Journal where I found it:
After stepping around a marked police patrol car parked at the front door, a man walked into H&J Leather & Firearms intent on robbing the store. The shop was full of customers and a uniformed officer was standing at the counter. Upon seeing the officer, the would-be robber announced a hold-up! and fired a few wild shots from a target pistol. The officer and a clerk promptly returned fire, and several customers also drew their guns and fired. The robber was pronounced dead at the scene by Paramedics. Crime scene investigators located 47 expended cartridge cases in the shop. The subsequent autopsy revealed 23 gunshot wounds. Ballistics identified rounds from 7 different weapons. No one else was hurt.
