Of Man and (Killer) Whales

Just three days after a six-ton killer whale battered and drowned his trainer in front of a horrified crowd, SeaWorld opened again this weekend in Orlando, San Antonio and San Diego. Tilikum, the Orca that did the killing, will continue life as a valuable stud who's fathered 13 calves — and as a performer. Critics are asking challenging questions. Can human beings ever know what a killer whale is thinking? Should orcas be released to sea rather than held in captivity to entertain human beings? We hear from both sides and look at the controversy about dolphins kicked up by The Cove, a documentary nominated for an Oscar.
