Animal Liberation Front is a leaderless, autonomous movement that has been linked to acts of arson, conspiracy, and terrorism. Founded in the United Kingdom in the 1970s, the group claims to support “direct action” in the form of burning research facilities and restaurants they deem to hold animal products. In 2003, individuals and groups closely affiliated with or members of the Animal Liberation Front (ALF) carried out significant acts of sabotage within the United States. They detonated improvised explosive devices at the facilities of two northern California companies targeted due to their connections with the UK-based firm Huntingdon Life Sciences. Additionally, they set fire to a large condominium complex under construction near La Jolla, California, resulting in an estimated $50 million in damages. ALF supporters also vandalized two newly constructed homes near Ann Arbor, Michigan, in March 2003. They are accused of damaging approximately 120 SUVs in West Covina, California, during the same year.
