I live in Minneapolis, and I'm not a Twitter user, but I've found that following news reporters on Twitter that are on-site has been the best way to get reliable information quickly during the protests. (I use nitter.net to follow them.) I don't even like Twitter, but I can say unequivocally that it's not "trash, bots, and trashy bots all the way down". It's been extremely valuable to me this week.
