About 50 Occupy Minnesota protestors listed off why they wanted to risk arrest at Steve Payne’s teach-in on Saturday. Some said their goal was “to end capitalism.” Others said they protested “because the Federal Reserve and banks stole trillions.” Or for others, the end result was “to make a change” or “to stop just talking about a revolution.” Those broader grievances, though, were tied to a more specific one on the ninth day of Minnesota’s nascent spinoff of the Occupy Wall Street movement that has swept the nation: the desire for shelter to continue protesting in the face of Minnesota’s frigid weather.
