The ACLU is aghast that the Federal Bureau of Investigation has monitored some of the activities of People for the Ethical Treatment of Animals (PETA). among other groups, according to this report. Not until Later in the story the report notes that the FBI has 150 pending investigations into potential terrorist activities by animal rights and environmental militants. The sort of activities investigated range from destroying research labs and experiments, sabotaging industrial equipment, and vandalism. At the very end of the story, it is noted that PETA has a long suspected association with the Animal Liberation Front, the ragtag group believed responsible for much animal rights terrorist activity. Given such ties, why wouldn’t we expect the FBI to monitor PETA events? And is such an investigation truly, as the ACLU claims, a threat to freedom of association? Despite my libertarian leanings, I’m quite skeptical.
