Tragedy! Cop guns down fellow Finest

"A drunken off-duty cop holding a man at gunpoint outside a Bronx White Castle was shot three times by a veteran officer in a tragic case of mistaken identity early yesterday, police and hospital sources said. "Drop the gun! Drop the gun!" the uniformed cop yelled." FULL STORY

Happens a lot. Maybe not every day, but drunken off-duty cops being mistaken for bad guys or getting mugged and shooting up half a neighborhood as they return fire is not unusual. Catch the movie Prince Of The City. NYPD truly feels the town belongs to them, and why shouldn't they? The citizens have been disarmed and anyone ELSE with a gun must be another cop or a bad guy. If it's another cop they're confronting over some nebulous wrong they soon find out then go get drunker and laugh it off. If it's just a citizen then there's big trouble. And NO ONE, not even other cops can stop them from teaching the clueless who really runs NY.

That particular White Castle sees a "unique" crowd. Everyone knows that the biggest mouth in the joint MUST be a cop so you part the line to let them go to the front, but that place sees some rawboned clientele who at times don't give good part.

Now we wait for the Mayor to start caterwauling that the off duty cops gun came from Florida.
