Furious that an NYPD officer was fired for killing a man by using a forbidden chokehold, the department's largest union is calling for the ouster of New York City Mayor Bill de Blasio and the resignation of Police Commissioner James O'Neill.

Delegates for the 25,000-member Police Benevolent Association issued two votes of no confidence against the mayor and commissioner Wednesday, the same day the department acknowledge there has been a drop in arrests since New York City police officer Daniel Pantaleo was fired earlier this month.

Judging by the high number of petty arrests conducted by the NYPD, the drop in arrests should not make the city any less safe. But it probably does affect the city revenue, much of it dependent on the poor people its arrests on petty charges like selling loose cigarettes.

The way the union sees it, any attempt at holding officers accountable reeks of "anti-police" bias and does nothing but demonize police officers.

According to the Wall Street Journal:

“For years, Mayor de Blasio has demonized police officers and undermined our efforts to protect our city,“ (NYPD union president Patrick Lynch) said. ”For years, Commissioner O’Neill has cravenly acquiesced to the Mayor and his anti-cop allies.”

The last time the police union issued a resolution calling for an NYPD commissioner to step down was in 2004, when the union demanded the resignation of then-Commissioner Ray Kelly in protest of disciplinary action taken against an officer who shot and killed an unarmed black teen in Brooklyn. Commissioner Kelly didn’t resign and served in the post until 2013.

“For years, Mayor de Blasio has demonized police officers and undermined our efforts to protect our city,“ he said. ”For years, Commissioner O’Neill has cravenly acquiesced to the Mayor and his anti-cop allies.”

Although the union has not called for an official work slowdown, there was a 27 percent decline in arrests during the week following Pantaleo's termination compared to the same period last year.
