An activist involved with the Oscar-winning documentary "The Cove" which shows Japan's annual dolphin hunt says a new video of a dolphin jumping out of an aquarium proves the cruelty of captivity.
Ric O'Barry says all dolphins in captivity should be set free. The latest video shows a dolphin suddenly leaping out of its tank during a show in southwest Japan. O'Barry says dolphins are used to roaming miles a day in their habitat, not swimming in circles doing flips at shows. He also stressed keeping dolphins in a concrete box is cruel, bombarding the animal with strange sounds and depriving its key sensory skill.
