Thirty-two animal activists were arrested today (April 20) during a four-hour protest at the University of California, Davis. They were charged with a range of violations: trespassing, resisting arrest, vandalism, and wearing a mask during the commission of a crime. Starting shortly before 11 a.m., 34 protesters held a brief demonstration in front of the campus's John E. Thurman Veterinary Diagnostic Laboratory -- site of the country's most costly destructive act by animal rights activists in 1987. The activists then walked west to the campus's California Regional Primate Research Center, where they spent the next three hours. They were joined by four additional protesters who had somehow entered the research center site earlier. These four stood on top of a partially constructed research facility, the Center for Comparative Medicine, that had been the site of arson last month. Following acts of civil disobedience, police arrested 29 adults and three juveniles. One protester claimed to be injured during an altercation with police. He was taken to Sutter Davis Hospital and released from the hospital later that afternoon. The 29 adults arrested and taken to the Yolo County jail were: • Nicole Dawn Briggs, no date of birth given, of Santa Cruz, charged with trespassing; • Stephanie Hope Ewton, 27, of Sebastopol, trespassing; • John Paul Goodwin, 24, of Memphis, Tenn., trespassing; • Brian Halverstady, 21, of Seattle, Wash., trespassing; • Dustin Curtis Hamann, 19, no hometown given, trespassing and vandalism; • Joshua Caleb Harper, 22, of Portland, Ore., trespassing; • David Patrick Hayden, 29, of Costa Mesa, trespassing; • Kevin Michael Keller, 19, of San Francisco, trespassing, resisting an officer and wearing a mask during commission of a crime; • Michael Ian Kennedy, 19, of Novato, trespassing; • Lisa J.

The three juveniles arrested were taken to the UC Davis police station or to juvenile hall. Two were born in 1980 and one in 1982; their hometowns were not provided. All were charged with trespassing; one additionally was charged with vandalism. Each April's World Laboratory Animal Liberation Week has typically been observed with protest rallies, graffitied sidewalks and buildings, acts of civil disobedience, and vandalized campus vehicles. The campus had seen little protest activity the past few years, however. In 1987, there was a $4.6 million arson fire at the campus's John E. Thurman Veterinary Diagnostic Laboratory. Although the letters ALF (Animal Liberation Front) were found painted inside that burned laboratory, no one was ever prosecuted for the fire, due to the lack of evidence. The building was eventually completed and now provides diagnostic services and information to help control animal diseases. The ALF also claimed responsibility for a March 18 arson fire on campus at the site of the partially constructed Center for Comparative Medicine, west of the main Davis campus. Damage, estimated at under $1,000, was confined to an area about 10 feet square. Originally scheduled for completion in 1998, the $10.3 million center is being built so that veterinary and human medicine researchers can combine forces to study serious viral diseases that afflict humans and animals. Research at the new facility will be targeted at prevention and control of such major ailments as AIDS, herpes, virus diseases, measles, leukemia and other types of cancer. During Picnic Day yesterday at UC Davis an estimated 30 protesters showed up at two animal events at the campus's annual open house. They demonstrated against goat milking and horse breeding.
