the officers may or may not have said a word, we don't have that information. What we do know is that the moderators asked him to step down, then to leave before the cops were called in. He was acting in a disruptive manner in a public forum, he has a right to free speech, but by acting like a fool and being disrespectful the the promoters, the Senator and the public in attendance the other peoples right to safety took over.
Stop condemning the police anytime they do something, you handicap them with this crap and soon you'll wonder where they are when you really need them.
