From Colorado, Boulder's radio station KGNU interviewed marchers in Colorado Springs who said that the peaceful marchers were teargassed by the police for no reason that the marchers could see. They were not near nor heading toward the Air Force Academy, just holding a routine peace march, which had been planned and announced in advance, but the police herded them off into a parking lot. I imagine there must be more to it but that's all I've heard so far.
