Police unions aren't the same thing as other unions. Most unions exist to equalize labor negotiation through collective bargaining, and police unions tend to include and align with the leadership in the organization that a union would traditionally be negotiating with. In practice they're a lot more like a military contractor than a union (in that their role is to prevent public accountability)

lol. I typed ubi is and the autocorrect put “unions.” It has been corrected . But it is kinda funny anyway.
