This one seems a little fishy. Wishing I had more knowledge about it.
Seems like he was arrested and charged because police thought he was protesting on private property, when he was actually on public property, but was still found guilty of trespassing anyways. But that may have to do with what he told the police his intentions were for being there as well.
Sorry, will do better later.Can you describe the link so I can decide if I want to click on it? That was one of the very few MadCow causes I supported. He was always crusading to get people to describe their links.
