Seaworld has long been a family favorite for its spectacular shows. Trained killer whales have been a special draw. But for members of People for the Ethical Treatment of Animals, what Seaworld is doing is enslaving killer whales. PETA lawyers are suing Seaworld. They argue the 13th Amendment does not apply solely to humans. Instead, they recommend that Seaworld replace real killer whales with robots. But if human laws apply to whales, shouldn't Tilikum be in jail for killing a trainer?
