The Animal Liberation Front (ALF) is an international, decentralized political and social resistance movement that engages in and promotes non-violent direct action in protest against incidents of animal cruelty. The ALF removes animals from laboratories and farms, destroying facilities, arranging safe houses, veterinary care, and operating sanctuaries where the animals subsequently live. Active in over 40 countries, ALF cells operate clandestinely, consisting of small groups of friends and sometimes just one person, which makes the movement difficult for the authorities to monitor. Robin Webb of the British Animal Liberation Press Office has said: "That is why the ALF cannot be smashed,
… Read more it cannot be effectively infiltrated, it cannot be stopped. You, each and every one of you: you are the ALF". According to the ALF's code, any act that furthers the cause of animal liberation, where all reasonable precautions are taken not to harm human or non-human life, may be claimed as an ALF action, including acts of vandalism causing economic damage. The ALF uses direct action techniques, including animal liberation, violence, and property destruction. Industries targeted include meat, dairy, animal testing, fur, other animal-based industries, private citizens, and government institutions.
