Animal Rights Activists Arrested in UC Attacks

From the looks of it, they aren't charging them with any firebombings or anything like that.

Crimes arrested activists are accused of

Oct. 21, 2007: A group of 20 protesters demonstrated outside of a UC Berkeley professor's home in El Cerrito. Some wore bandanas to hide their faces. They trespassed on his front yard, chanted slogans and accused him of being a murderer because of his use of animals in research.
Jan. 27, 2008: Demonstrations, including chalking, in front of the homes of several UC researchers.
Feb. 20, 2008: A group of five protesters tried to forcibly enter the Westside home of a UC Santa Cruz researcher during a child's birthday party. The researcher's husband was hit during the demonstration.
July 29, 2008: Fliers left at Caffe Pergolesi in Santa Cruz that contained the names, addresses and telephone numbers of several UCSC scientists. The fliers said the researchers were 'murderers and torturers alive and well in Santa Cruz' and stated 'We know where you live. We know where you work. We will never back down until you end your abuse."

The home invasion is bad, but leaving fliers? Chalking? I've got no problem arresting violent protesters and jailing them for years, but most of this case sounds pretty lame.
