> It’s kind like human rights - the majority of people who are at risk of having them infringed are unpleasant or unsympathetic characters.
I think some people have a view of "human rights" that fixates on and elevates "unpleasant or unsympathetic characters" but I don't think it's intrinsic to the concept of human rights.
> I’d argue a cliché “upstanding law-abiding citizen” type doesn’t generally have that much to fear from a police interaction. They are generally being dealt with on a presumption of good faith, and have at least some access to leverage and ability to push back against unfair treatment. Someone who’s already been identified as a “scumbag” doesn’t, and that is why their treatment is more illuminating.
Illuminating of what exactly that would make their view more "important" (as stated above) than the views of law abiding citizens?
> There are many of them and they vary by region. Police very observably interact differently with richer versus poorer groups, for example, or with groups from different ethnic backgrounds.
I think if you break it down more granularly, you'll see that what police interactions vary more within, for example, ethnic groups, than between ethnic groups, based on characteristics such as past criminal history, etc.
