What's the de-escalation plan for the protesters? Have they even indicated the things that would make them stop protesting / rioting?
I mean something practical, not just "we want justice!" What do they want other than just having the perpetrators put in jail? If that won't appease them, what will? I don't think a public execution is a realistic demand, even though I'm sure that what some people want.
Well, if the police would stop brutalizing and murdering people it'd probably be a good start. So the tear gas, pepper spray, rubber bullets, and vehicular assault
stopping would be a good starting point. Could work on proper prosecution for the murderer and his accomplices that kicked this latest batch of protests off, too, maybe -- that seems to be the major call for Minneapolis in particular, they don't just want the direct murderer they want the fuckers who sat there and helped him, too. Then cleaning up police in general, really. Disbanding precincts that have problems (which might be all of them I'unno :V) and replacing them wholesale might be a good step 1.
Really, if you want to appease the protesters shit is pretty damn straightforward. Put the boot to the jackboot thugs in uniform terrorizing communities and maiming/murdering people with near impunity, get economic relief for areas in serious trouble. None of this had to happen, and if you remove or mitigate the underlying causes (shit lives, bastard cops making them worse) it can stop. If you're more interested in brutalizing and maiming protesters, well, it can keep going I guess.
