In Charlotte, N.C., drug warriors got a tip that someone there was distributing cocaine, so they burst into the suspect home using a flashback grenade. Four men were there playing cards. One of them, 56-year-old Charles Irwin Potts, was wearing his legally owned and carried handgun. The drug warriors shot him four times in the chest, killing him. The three witnesses, who believed the house was being robbed, said Potts' gun never left its holster. The drug warriors found no cocaine, and made no arrests. An internal investigation vindicated the agents.
