> How you get any of those things by demonizing the police and making it a left-vs-right political issue is beyond me.

I get this vibe as well. I want to interpret this charitably, but this seems antithetical to good faith participation. It feels like these people don't actually care about police brutality--any arbitrary partisan issue would suffice. Of course, I'm sure I'm misreading the situation (even though social psychology's most replicable studies predict exactly this sort of hyper-partisanship).
