Judy, they were breaking the law! "A group of about a dozen protesters sat on a path with their arms interlocked as police moved in to clear out a protest encampment affiliated with the Occupy Wall Street movement Friday."
"The school said 10 protesters arrested were given misdemeanor citations for unlawful assembly and failure to disperse." http://www.cnn.com/2011/11/20/us/california-occupy-pepperspray/index.html
