PETA Animal Protection Campaign

Undercover investigations
PETA sends its staff undercover into research laboratories, factory farms, and circuses to document the treatment of animals, requiring them to spend many months as employees of the facility, making copies of documents and wearing hidden cameras. By 2007, it had conducted 75 such investigations. It has also produced videos based on material collected during ALF raids. Some investigations have led to lawsuits or government action against the companies or universities. PETA itself faced legal action in April 2007 after the owners of a chinchilla ranch in Michigan complained about an undercover inquiry there, but the judge ruled in PETA's favor that undercover investigations can be legitimate.
Notable cases include the 26-minute film PETA produced in 1984, Unnecessary Fuss, based on 60 hours of researchers' footage obtained by the ALF during a raid on the University of Pennsylvania's head injury clinic. The footage showed researchers laughing at baboons as they inflicted brain damage on them with a hydraulic device intended to simulate whiplash. Laboratory animal veterinarian Larry Carbone writes that the researchers openly discussed how one baboon was awake before the head injury, despite protocols being in place for anaesthesia. The ensuing publicity led to the suspension of funds from the university, the firing of its chief veterinarian, the closure of the lab, and a period of probation for the university.
In 1990, two PETA activists posed as employees of Carolina Biological, where they took pictures and video inside the company, alleging that cats were being mistreated. Following the release of PETA's tapes, the USDA conducted their own inspection and subsequently charged the company with seven violations of the Animal Welfare Act. Four years later, an administrative judge ruled that Carolina Biological had not committed any violations.
