BLM's regional chapters are all independent and don't answer to a central authority. But, the founders of the Movement For Black Lives: Patrice Cullours, Alecia Garza and..........I'm forgetting the third now, have had generous corporate and foundation grants dumped over them, and no doubt the donors intended for them to reign in radicals all across America and just run a more limited operation, doing protests and marches and maybe making up a DSA committee or something.
But, with everything going on, nobody can control what's going to happen on the streets, and that makes a lot of businessmen who want wave BLM banners and claim a show of support nervous, because they want a nice, respectable BLM movement that won't break windows, throw stuff at CNN reporters and cameras etc..
