Live mics are a problem sometimes.
Check it out:

University of California President Janet Napolitano told a fellow regent that they “didn’t have to listen to this crap” as protesters yelled about potential tuition hikes at the university.

According to KPIX-TV, protests began during a regents meeting Wednesday in San Francisco. The cameras stayed on the UC regents who seemed confused. That’s when Napolitano leans over and says, “Let’s just break. Let’s go, let’s go. We don’t have to listen to this crap.” Her mic was on at the time and caught the comment.
