Timothy Treadwell, Bradley University attendee and star of the documentary, "Grizzly Man" was obviously a lunatic. He thought he was a bear and for over a decade he filmed bears and tried befriending bears in Alaska. SPOILER: He gets eaten by a bear. By the way, it's an exceptional film and wildly entertaining if only to see this passionate man act like such a loony toon. So, why wasn't Timothy Treadwell admitted to a mental hospital? Do you have to be a threat to other people or can it by yourself as well? Because the outcome proves that his lunacy cost him his life?
