Animal Liberation Front (ALF) Law and Legal Definition
The Animal Liberation Front (ALF) is an international, underground leaderless resistance that engages in illegal direct action in pursuit of animal liberation. ALF is 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. In 2005 the ALF was included in a United States Department of Homeland Security planning document listing a number of domestic terrorist threats on which the U.S. government expected to focus resources.
