Lastly, removing elected officials varies from place to place. It's universally easier than removing a sitting president and has the advantage that it's actually possible which isn't always the case for typical police (who are almost universally loathed for their lack of accountability and public recourse options).

In theory this sounds great, but in practice I'm not so sure. The average person seems to get stonewalled at best, harassed or targeted at worst, when trying to file formal complaint against an officer. I can't imagine trying this against a sheriff that is popular with the police unions.
