In animal rights and welfare, open rescue is a direct action of rescue practiced by activists. Open rescue involves rescuing animals in pain and suffering, giving the rescued animals veterinary treatment and long-term care, documenting the living conditions, and ultimately publicly releasing the rescue and documentation. Open rescue's public nature contrasts with clandestine animal rights activism. Open rescue activists typically publish their full identities. Open rescue is nonviolent towards humans and other animals, although some groups practice property damage. The open rescue method was largely developed by Animal Liberation Victoria (ALV) Rescue Team, based in Melbourne. Inspired by satyagraha, the method and philosophy used by Mahatma Gandhi in the struggle for independence for India, the ALV developed this method in the 1980s and has since been conducting investigations and open rescue operations, actions which reportedly have been well received by the public. At one point an Australian MP joined in the rescue operation of factory farmed piglets. While not called open rescue, several other activist groups began engaging in activities similar to open rescue around the same time. People for the Ethical Treatment of Animals rescued several monkeys in 1981 from a lab in Silver Spring, Maryland and sparked discussion in The Washington Post. In 1999, Patty Mark of the ALV presented open rescue at United Poultry Concern's Direct Action for Animals Conference. Displaying the positive results of the open rescue actions in Australia and by comparing videos from an open rescue action and a clandestine action, she managed to convince a number of people of the usefulness of open rescue both on the grounds of compassions for animals and on the grounds of the reception by the general public, opening for the open rescue method on the international arena. Soon after this, Compassionate Action for Animals (US) adopted the method, and other organizations followed. Activist Adam Durand with Compassionate Consumers conducted an open rescues at a Wegmans' egg farm in 2004.
