You can form one. Generically, it's called a political party, but there are special-interest groups like the NRA representing gun-owners, or the PTA, which represents families.

I don't think anyone is arguing there shouldn't be police unions. However, those should be reformed as open and transparent organizations which support for law-and-order, good working conditions for police officers, and similar.

Those should not be secretive organizations which support police violence, racism, protect bad cops, and sometimes engage in organized crime.
