Plus a change, plus c’est la mme chose—from 1992. (bolding mine)

Thousands of off-duty police officers thronged around City Hall yesterday, swarming through police barricades to rally on the steps of the hall and blocking traffic on the Brooklyn Bridge for nearly an hour in the most unruly and angry police demonstration in recent memory…

the harsh emotional pitch reflected widespread anger among rank-and-file officers toward the Mayor for his handling of riots against the police in Washington Heights last July, his refusal to give them semiautomatic weapons and his appointment of an outside panel to investigate corruption…

Mayor Dinkins, who was not at City Hall during the demonstration, denounced the protest as “bordering on hooliganism” and said he held the P.B.A. president, Phil Caruso, responsible for what happened. He accused Mr. Caruso of inciting his members’ passions…

Mr. Dinkins said Mr. Giuliani had egged on the protest irresponsibly for political reasons. “He’s clearly, clearly an opportunist,” Mr. Dinkins said. “He’s seizing upon a fragile circumstance in our city for his own political gain.”…

The officers alternated chants of “No justice! No police!” with slogans like “The Mayor’s on Crack.”

Many officers wore T-shirts saying “Dinkins Must Go!” Hundreds carried hand-painted signs with sayings like “Dear Mayor, have you hugged a drug dealer today,” “Dinkins, We Know Your True Color — Yellow Bellied.”…

They did virtually nothing to control the crowd. At one point, a New York Times photographer who was taking pictures was surrounded by demonstrators, punched in the back and shoved. A police lieutenant told the photographer, Keith Meyers, that he should leave the bridge. “I can’t protect you up here,” the officer said. A New York Times reporter, Alan Finder, was also kicked in the stomach.
