The typical cop personality rates high on fear, conservatism, authoritarianism and lack of empathy. Even the ones who don't openly abuse get off on being part of a dominant gang in society. None of this means they are useless or terrible at all times, but they have to be carefully monitored and told to get back in line. Elected authorities, the courts and the public need to be on these guys constantly making sure the really criminal ones are fired immediately and the lurking sociopaths (like the Golden State Killler, hired by police departments twice) are exposed by their own as soon as possible.
Don't take it so hard that people hate you—you can make it all better by renouncing your support for militias and white supremacist terrorists—which, by the way, your oath to the Constitution mandates you do. You can stop using your "tools" to harm and kill.
