Animal Rights Groups at Odds Over Proposition 12
Warning: The video below contains graphic images that some viewers may find disturbing. SACRAMENTO -- Undercover video showing the treatment of pigs at a farm in Kentucky was used to make a push for Proposition 12. Mercy for Animals planted a worker at the farm for four months and gathered video of pigs being housed in gestation cages, where they can barely move. The animal rights groups says pigs were gnawing on bars because of the stress and boredom.
