The law needs to land on these extremists.
Actually, these "activists" fit every definition I have ever seen or heard for "Terrorist" and should be arrested and tried as such. Same goes for members and supporters of many of the Peta, ALF, ELF, and other similar groups and organizations. Fifty years ago, the wrath of a community would have been "visited" upon them, just prior to their being found and arrested by local law. And most lawyers at that time were actually interested in "Justice", not in the self-grandizement currently extant in the "legal" profession.
