Apparently the cops are running out of less-lethal munitions.
A wonder that they had any in the first place.
And it's all going to depend on the local actors. Is the local city government backing the police to the hilt, or are the divisions already showing? Just how organised are the rioters and the protestors? Have the usual brigade of bootlickers (Oathkeepers etc) started to mobilise and what is their ground level game like? How badly is unemployment hitting the city, and are compounding factors from Covid-19 making that situation worse or not (lets be honest, they almost certainly are, though to what degree etc). Hell, what is the weather going to be like for the next week?
That's what I'd be looking at, nuts and bolts stuff, organisational research to understand who is likely to crumple first.
I can answer some of this for Minneapolis.
The government is not backing the police at fucking all. The Minn. Mayor is trying to play peacemaker about it (while using the sort of language that is Politician for “you’re a bunch of fucking idiots and you’re gonna get yours now”) — but the St. Paul PD across the way said outright that Minn. PD fucked the dog so bad that they’re refusing to honor the mutual aid agreement the cities have. So the answer is the PD is basically a rogue actor now. No support at all.
Minn. also has gun lunatics showing up, but they’re doing two things and surprisingly doing them well:
Defending stores from looters, without half as much macho posturing about it as usual some fucking how,
And backing up the protestors directly, some of them even catching rubber bullets and canisters in the chest for their trouble.
I don’t think the threepers or other white nationalist scum are involved. If they were I think they’d be dealt with fast, right now: the general atmosphere is supportive of the protest.
The rest I can’t really be sure, but Minneapolis is doing very badly in general right now, even before all this.
I do know the protestors are either gun nuts or people who legitimately feel like they have nothing to lose, backs against the wall, “what are you gonna do, /shoot/ us” kind of mindset. Word is that they are not looting these stores for money, clothes, electronics or food, they’re looting them for supplies to clean gas off faces and help with field medic shit. Lots of Gatorade and bottled water and milk going out. I’m not sure if that speaks to being prepared to go toe to toe or if it means they aren’t mentally prepared for an extended go at the PD.
