1999: Animal Rights Organization Threatens Scientists, Sends Letters Booby-Trapped with Razor Blades

Eighty university researchers receive threatening letters booby-trapped with razor blades. One of the letters, sent to a Harvard researcher, says: “You have until autumn 2000 to release all your primate captives and get out of the vivisection industry. If you do not heed our warning, your violence will be turned back upon you.” The “Justice Department,” an animal-rights organization and an offshoot of the Animal Liberation Front (ALF—see 1976), claims responsibility for the mailing.
