What makes police unions different from other unions is cops have a lot more power to make life miserable for their political enemies. They have effectively a legal right to harass anyone they'd like.

The worst a teachers union can do is strike.

Cops can assault and murder people then claim self defense. It's unlikely another cop will arrest them, and it's unlikely a prosecutor will actually do their job in prosecuting them.

This sort of undue power is what enabled Joe Arpaio to setup a concentration camp. That's somewhat the extreme of what cops can do. And he did, eventually, get prosecuted for it (though he was pardoned). But that was literally after years of those sorts of stunts. [1]

I can guarantee that Arpaio isn't the only corrupt cop out there. He just got too much national attention which ultimately ended his career.
