Here is a typical usurpation of someone else's rights (right to speak) by some typical Occupy reprobates. What they don't get is this: There is a reason that Congresswoman Michele Bachmann was given the microphone in this situation, and they were not. She was given the mic, given the floor to speak, because based on her past accomplishments and her current status as someone who is running for election to the highest office in the land, it has been estimated that she may have something to say which is worth hearing.
Based on the non-accomplishments of those who disrupted her speech, it was (correctly) estimated that they have nothing to say that is worth hearing. In situations like this, such people have a duty to shut up.
