I didn't say you were more "able" (though if you don't believe different levels of ability exist, I'm not sure what to tell you...). I said people have different available resources. If you're working a part time/minimum wage job with no car (which is just one example that covers a massive number of people), then you don't have the option to decide you don't like the policing in your neighborhood and just up and move. There are countless other scenarios that would similarly limit someone's options to simply move somewhere else if they were being harassed by the police.
My experience is limited to the US, but in most US jurisdictions, the police chief works for the local municipal government and goes through the same hiring process as any other city/town employee.
Different levels of ability may exist, but the thinking “if people aren’t living the way I want to live, it must be because they can’t” is pervasive. By and large, people have agency. Assuming they are passive blobs forced into situations beyond their control is both disrespectful and out touch. I frequently speak with people who have been in far worse situations than “low income and no car”, who have been able to travel the country and reach their desired enforcement zones.
In my experience, heads of policing candidates each put their “mission statement” and intended enforcement levels in an essay/Q&A hosted online by the local news. The community can read through the statements and choose the policing they feel most appropriate for their situation. If communities have chosen levels I don’t like, I respect their ability to do so - and live elsewhere.
If your community doesn’t have elected control over their police, and you want it to - I suggest you live elsewhere. Oregon is lovely this time of year.
