There's no excuse for this kind of behavior but it happens in every election. There are always hecklers, and sometimes the candidate's voice gets drowned out. There are also ways to deal with hecklers. This doesn't reflect well on those who did it but honestly the failure to handle it doesn't reflect well on Herman Cain, either. The only person tangentially involved who wasn't implicated in any way was Ron Paul, unless it can be shown that he set this up.
