Police brutality is a problem. It stems from having a police state, so no "reform" of the police without addressing the larger problem will do anything except make it worse.
BLM is another problem - a larcenous, racist and Marxist group that hides behind a name. Many people back BLM because they have no clue what it means - much like the people who back Marxism elsewhere. I would say useful idiots, but the power of media is not something to be dismissed. Smart people can be fooled too.
And since black lives are of particular concern to you, so what are you doing to save black lives? I don't think any have been saved by your ranting here, or by your avatar. How many have you saved?
