Meanwhile, in Minnesota, a group of video activists say they’ve been detained and stripped of their video equipment a week ahead of the Republican convention. Members of the group Glass Bead Collective say they were stopped by three police cars as they rode their bikes in Minneapolis. The activists have been involved in grassroots media efforts to document protests and police crackdowns. They helped distribute the video showing a police officer’s assault on a bicyclist in New York City last month. The video has gotten more than one million hits on YouTube.
