I went to the DNC in 2004 and 2008. Both times I heard from friends later that TV had been focused on riots, which confused the hell out of me, because I didn't see anything. There was some obnoxious stuff at the 2008 convention in Denver, we had to walk a gauntlet of ugly pictures of dead fetuses going in and out of the convention center. But in neither case were there any disturbances.
