A Miami cop shot and killed a naked man who was chewing on another man's face-- on an exit ramp of a major causeway.

A woman flagged down a police officer after seeing two men fighting on a walkway of the exit ramp. The officer approached the men and saw the naked man gnawing on the face of another man. The officer told the man to back away, but he ignored the officer, so the policeman shot him.

Amazingly, the man kept chewing on the other man, so the officer fired a few more shots.

The man who was attacked is in intensive care.
