Vivisectors like to claim that a water hose slipped through someone's window or a message chalked on their sidewalk is terrorism.
Real, genuine, kill-people terrorism was practiced by vivisector Bruce E. Ivins. He has been in the news recently. He killed himself, apparently, after learning of an immanent federal indictment naming him as the source of the 2001 anthrax letters that killed five people and made seventeen others ill. Ivins worked at US Army Medical Research Institute of Infectious Diseases (USAMRIID) in Fort Detrick, Maryland.
A few of his forty or so published scientific papers:
1988 Recent advances in the development of an improved, human anthrax vaccine.
1989 Influence of body weight on response of Fischer 344 rats to anthrax lethal toxin.
1994 Efficacy of a standard human anthrax vaccine against Bacillus anthracis spore challenge in guinea-pigs.
1998 Comparative efficacy of experimental anthrax vaccine candidates against inhalation anthrax in rhesus macaques.
2001 Efficacy of a human anthrax vaccine in guinea pigs, rabbits, and rhesus macaques against challenge by Bacillus anthracis isolates of diverse geographical origin.
2002 Anthrax vaccine efficacy in golden Syrian hamsters.
2004 Defining a serological correlate of protection in rabbits for a recombinant anthrax vaccine.
2006 Duration of protection of rabbits after vaccination with Bacillus anthracis recombinant protective antigen vaccine.
2007 Determination of antibiotic efficacy against Bacillus anthracis in a mouse aerosol challenge model.
2008 Efficacy of Oritavancin in a Murine Model of Bacillus anthracis Spore Inhalation Anthrax.
If an animal rights activist had stolen anthrax spores and then sent them in the mail to a few vivisectors, laws even more draconian than the AETA would have snapped into place instantly. Harassment of activists by law enforcement and other government officials would have escalated wildly.
A vivisector sends anthrax spores through the mail to media and government officials and all you hear is the wind.
