“A Miami police officer on Saturday fatally shot a naked man who was chewing on the face of another man on a downtown causeway off-ramp,” the AP reports. “Witnesses said that a woman saw two men fighting and flagged down a police officer, who came upon a naked man mauling the other man. The newspaper quoted witnesses as saying that the officer ordered the naked man to back away, and when he ignored the demand, the officer shot him. Witnesses said that the naked man continued his attack after being shot once, and the officer shot him several more times.” Aside from the obvious zombie alert, there’s a lesson here: keep shooting until the threat stops. Or run. That is all.
