The tweets didn’t offer “sending in the police” it threatened to send the military in. Which isn’t the police.
Word matter. The fact I’m m reading this comment here is sad.
Needless to say there's also been some reporting and concerns of provocateurs among the protesters here as well using it as an excuse to inflame riots or start looting.
Maybe you didn't see that part because Twitter has hidden the tweet?
The looting in Minneapolis is a) rather ancillary to the larger protests against the police, b) an American tradition going back to colonial times, and c) a mix of opportunism and antipathy to US hypercapitalism. A few small stores have been damaged but the destruction has mainly been targeted against corporate retail outlets.
Personally I have never been part of a riotous protest, but in an academic sense I believe that destruction of commercial property does more to force a change in police activity than destruction of police cars and other public property (things that ultimately belong to the people themselves).
You can bet that there are more powerful people in the business community there, than on the police force.
I don't believe this is actively in the mind of most rioters, but I think it is part of the reason that rioting has a major impact on American politics.
That's reminiscent of the very brutal police practices that sparked this chaos in the first place.
Shooting rubber bullets at rioters and looters is standard practice pretty much everywhere in democracies, and in non-democracies they tend to go straight to lethal ammo.
