Beverly Hills Cop

I’ve decided to spend the evening eating pizza and watching Beverly Hills Cop for the first time in about 30 years. I am struck by the opening shots of an already-ruined Detroit; I thought its ruination was more modern than that but it looks to have been a shithole even in the mid-80s. A George Floyd-related thought: I only hear cases of police brutality in Democrat strongholds like California and Minneapolis; why?

More blacks, of course – that is one explanation. Does it suffice? Why are the cops so prone to fatal violence in Democrat strongholds? Does Democrat rule create conditions so chaotic & bestial that cops necessarily become Punisher-esque enforcers? Or are these incidents even arranged by higher political powers?
