This incident says much about the mindset of Democratic voters even in South Carolina. Bill Clinton was speaking on behalf of his wife Friday, and when a vet raised the issue of Benghazi, not only was he booed by the audience, he was escorted out of the hall.
Daily Caller has more. There was a woman involved.
Here is a longer video.
It seems to me that while the woman was being disruptive, the man was participating in a legitimate q and a and got a quick hook from security when he raised the issue of Benghazi. Be that as it may, it is the reaction of the crowd that I find most disturbing.
