Peaceful protesters trapped by riot police in Denver. Is St. Paul next?

I hope to God this doesn't happen in St. Paul next week: Last night in Denver, peaceful protesters were trapped by riot police and targeted with paintballs and teargas, according to the American News Project. The Republicans are likely to draw even more protesters than the Dems, and if you've been to St. Paul, you know that the topography -- hills, a bluff, the river, some walled roads near the RNC venue -- could add to the chaos. Let's hope things stay relatively calm.
