Yesterday, a Chicago jury ruled that two of the nation's most militant anti-abortion groups violated anti-racketeering laws by staging protests that used fear and violence to shut down two abortion clinics. Last weekend in the Twin Cities, protesters staged a violent demonstration in order to prevent a group of neo-Nazis from holding a press conference. The nature of political protests have changed over the past 30 years according to Jeffrey Broadbent, a professor of sociology at the University of Minnesota. He says compared to the 1960's, today's protests are considered a more legitimate way of participating in democracy...but they also carry a greater potential for violence.
