From the Philadelphia Inquirer...
Six members of Stop Huntingdon Animal Cruelty were convicted at a 2006 trial in New Jersey of conspiracy to violate the 1992 Animal Enterprise Protection Act. The law, since revised, aimed to protect animal research laboratories from illegal, sometimes violent protests.
The group was formed to protest the activities of Huntingdon Life Sciences in Franklin Township, N.J. The company had been a target of animal activists since video footage surfaced on television in the 1990s depicting animal abuse at its laboratory in the United Kingdom.
Huntingdon used mostly mice and rats , but also some dogs, monkeys, fish and guinea pigs , in its research in New Jersey.
The activists posted the home addresses of Huntingdon officials and contractors on the group's Web site, and harassment, vandalism and violence sometimes followed.
