The NYPD's rank and file police officers protested a lower-than-expected pay raise last night outside Gracie Mansion. "The mayor will feel the anger of the police force of New York City," PBA President Pat Lynch told CBS as a few hundred cops blew whistles and chanted their "one-term mayor." But turning your backs at the funerals for murdered police officers is a tough act to follow.

The 24,000 NYPD officers represented by the PBA haven't had a contract in six years, and rather than continue to negotiate with the City, requested arbitration. Howard Edelman of the state Public Employment Relations Board, ruled that the officers should receive a 1% pay raise per year.

As NYPD Commissioner Bill Bratton put it on Monday, "[Patrick Lynch] rolled the dice, and he lost on this roll of the dice."

Speaking to reporters at the parade for Veterans Day yesterday, de Blasio pointed out that the NYPD was hiring 1,300 new police officers and that the City has invested in new technology for beat cops.

"The PBA leadership decided on arbitration. We said throughout that process our door was open. Our door is still open to talk about a long-term contract, but it will be part of the pattern that all the uniformed services have agreed to," the mayor said.

Politico reporter Laura Nahmias had the most colorful coverage of the demonstrations:

Lynch's PBA also protested low pay raises in front of Mayor Bloomberg's UES townhouse in 2004, but these demos seem tame compared to one afternoon in September of 1992, when 10,000 NYPD officers converged on City Hall to protest the creation of the CCRB.

Soon-to-be GOP mayoral candidate Rudy Giuliani gave a speech for the protesters, some of whom "flooded the bars along Murray Street and drank openly on the street during the speeches," according to an amusingly frank Times report.

At 10:50 A.M., a few demonstrators chanting "Take the hall! Take the hall!" flooded over the barriers and into the parking lot in front of City Hall, meeting no resistance from the police on guard. Cheering and screaming, thousands of others poured through from every side of the park and seethed up the hall steps. Some mounted automobiles and began a raucous demonstration, denting the cars.

Shortly before noon, thousands of them blocked traffic on the Brooklyn Bridge, chanting "The mayor is on crack!"

During most of that time, there were no uniformed officers on the bridge, though four officers on scooters arrived shortly after noon. 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.

Lynch apparently ended last night's protest on the early side with a pledge: "We'll be back."
