Louie Psihoyos, the Director of the Academy Award-winning documentary "The Cove" and the Oceanic Preservation Society, has released raw, unedited footage of the dolphin slaughter in Taiji, Japan, as part of a response to a Newsweek story that challenges the veracity of the documentary, and included claims the filmmakers created the "lurid" bloody water of the dolphin hunt "with special effects."
