Those banners will be short lived...
I think that law enforcement in the Twin Cities (and suburbs) are in for a rude awakening when the professional trouble makers roll into town for the convention. I’ll wager that they will be ill-prepared for the crap (literally) that they will encounter on the streets.
Hopefully, they’ll be paying real close attention to what goes on in Denver and just maybe, they’ll realize that they will be in the fight of their lives.
