The Primate Freedom Project (PFP), a group with chapters around the U.S. that describes itself as "dedicated to ending the use of nonhuman primates in biomedical and harmful behavioral experimentation," has had a key role in the campaign against the University of California.

PFP set up a Web site dedicated to ending "the use of primates in biomedical and harmful behavioral experimentation" at UCLA. The Web site included a "target" list of UCLA personnel, along with their photographs and home addresses, but also featured a disclaimer saying that "those who consider themselves part of the Primate Freedom Project UCLA chapter, do not engage in or encourage any illegal activities."

Several of the individuals listed as targets on the PFP Web site have been victimized by the Animal Liberation Front (ALF), the most active extreme animal rights movement in the country, and Animal Liberation Brigade (ALB), a moniker used by an apparent animal rights extremist cell has claimed responsibility for setting off pipe bombs at the offices of two companies with ties to animal testing in 2003.

In spite of the disclaimer stating that it does not encourage criminal activity, PFP has applauded the work of ALF and ALB targeting UCLA personnel identified on its Web site. For example, following the attempted firebombing of the home of Lynn Fairbanks, the director of the Center for Primate Neuroethology at UCLA, on June 30, 2006, a PFP spokesperson said that the director "is riding a gravy train to personal gain, nothing else, and I hope the ALF stops her in her tracks." In addition to posting Fairbanks' address and photo on its Web site prior to the incident, the PFP site had featured a flyer intended for "distribution in her neighborhood."

PFP was named in a restraining order UCLA obtained in early 2008; as a result, the group was currently prohibited from posting personal information about UCLA faculty on its Web site. The site has been taken down.
