Occupy Baltimore "mic checked" Karl Rove at a symposium speech on my undergraduate campus this week (article and video):

Like the majority of my friends at Hopkins I'm no fan of Karl's, but everyone I've talked to there has been pissed about it. A big complaint is that the Occupiers planted in the audience were not Hopkins students, but they felt justified in disrupting the entire event for everyone.
The Milton S. Eisenhower symposium is a year-long speaker series run by Hopkins students and funded by the university, and though it is primarily for Hopkins students, faculty and staff, it is free and open to the public in an effort to give back to the Baltimore community. They've had some pretty controversial speakers in the past (and the protestors that come with) but no one has ever actually tried to derail the speaker like this, as far as I know.
In the Youtube video you can hear booing in the background from the other attendees at the Occupiers. Most of the people I know who were there don't agree with Karl Rove's politics, but they wanted to hear what he had to say. IMHO the protestors' actions were in very poor taste.
