billy, at the time that you had met him, he was, if this is in fact his writing, there's no reason to believe it's not, that he was in the middle of a very tormented period in his life. he said this note, he was trying to write it as a form of therapy. there isn't enough therapy in the world that can fix what's really broken. also said he couldn't gracefully articulate my thoughts in light of the storm raging in my head. have you read any of this note? what kind of insight does it give us as to what might have been happening in his life? >> i haven't actually read any of the manifesto, i've heard quotes of some of the things he said. and again, the only thing i can say about that was he hid that really well. obviously he was some serious distress and in real despair.
