There are three major police unions in New York City. The Police Benevolent Association (which represents line officers), the Detectives' Endowment Association (detectives) and the Sergeants Benevolent Association (supervisory officers).
In 2020, the leader of the New York City Police Benevolent Association, Patrick Lynch, endorsed Trump in the presidential election, and appeared at the Republic National Convention to support him.
The Sergeants Benevolent Association also endorsed Trump; their leader at the time, Ed Mullins, appeared in an interview on Fox News with a QAnon mug, but has since left the position after his home was raided by the FBI. Prior to that, he was docked vacation time after he tweeted a screenshot of confidential police records concerning the mayor's daughter.
The Detectives' Endowment Association endorsed ... please attempt to suppress your surprise ... Trump as well.
In short: if your perspective is that police unions are run by liberals simply because they're unions, you are not paying attention to the facts.
