Mary Katharine Hamm tosses the narrative and examines the data.
One public calendar, compiled by RedState.com, lists more than 400 congressional town hall meetings in the month of August. It's likely not an exhaustive list, but it represents an average of more than 13 live town halls conducted per day in America during the monthlong span. At these meetings, there were fewer than ten documented incidents that could be described as violent, and most of them involved very little physical contact.[...]
In more than 400 events: one slap, one shove, three punches, two signs grabbed, one self-inflicted vandalism incident by a liberal, one unsolved vandalism incident, and one serious assault. Despite the left's insistence on the essentially barbaric nature of Obamacare critics, the video, photographic, and police report evidence is fairly clear in showing that 7 of the 10 incidents were perpetrated by Obama supporters and union members on Obama critics. If you add a phoned death threat to Democrat representative Brad Miller of N.C., from an Obama-care critic, the tally is 7 of 11.
