Earlier quoted context omitted.
Policing in the USA, to a nearby outsider, appears to be more about enforcing societal norms than safety or laws. It seems to me they harass anyone they perceive to be abnormal. As a delightfully abnormal human, I'm very glad I was born just north of the 49th parallel. It's not perfect, but I do feel free to be myself.
As a weird person who grew up in the USA (and eventually left for just this reason), I can attest to the accuracy of this analysis. I even wrote about it recently: https://sneak.berlin/20200628/the-problem-with-police-in-ame...
Police do in fact exist to enforce the law. It really is that simple.
