No, not in the aggregate. Local governments get a lot of funding from state and federal governments, which are in turn funded by federal and state income taxes and property taxes, but those funds largely go to support schools and housing programs. I’m sure there are some federal and state transfers to cops, but it’s a small portion. After that, it’s mostly sales taxes, excise taxes and service fees. There are a lot more not-rich people than rich ones.
Cops support wealthy people because wealthy people have power. They’re the ones who run things, and the cops work for them.
Edit: I shouldn’t say ‘no’. Numbers are difficult to find. But I doubt that income taxes from rich people constitute a greater portion of a cop’s salary than all other revenue sources, and I doubt that rich people contribute more revenue to sales taxes, excise taxes, service fees than all other people combined.
