Ayers protested again.

FoxNews.com - Students at the University of Colorado built a 3-foot by 3-foot "Free Speech Cage" in preperation for the appearance of radical professors Ward Churchill and William Ayers. Sean Daly, a supporter of the two radicals, called the "free speech cage" a mockery of "the so-called free speech zones." Organizer Aaron Smith waved away dissent by saying that "Mr. Ayers and Mr. Churchill have been similarly targeted for their unpopular political beliefs." The University had to beef up security for the event, costing the students an additional $3,000. Churchill was fired from the University in 2007 for "repeated misconduct, including plagiarism." William Ayers was a co-founder of a group responsible for several domestic terror bombings. Churchill referred, in one of his earlier writings, to the 9/11 victims as "little Eichmanns," a reference to a Nazi war criminal. So far fewer than 100 tickets had been sold.
