Since at least 2006, Nassau County Police Department's deadly force investigators have never ruled an officer's actions unjustified, Newsday reports.
A Nassau County police officer shot an unarmed man in the back. Another intentionally ran down an unarmed man with his squad car, costing him a leg. Still another shot an unarmed cabdriver after a night of drinking off duty.
The investigation into Nassau's use of deadly force found cases where officers fired on suspects after incorrectly believing they were armed, shot people later convicted of no crime at all, and took action that a jury would later call excessive, resulting in one civil settlement of more than $15 million.
