 Look, I was asked that question last night. I'll give you the same answer I gave some reporter last night. And I said, we don't know what caused it. I mean, we don't know why this guy went off. And, you know, maybe, look, the FBI will do a very, very good job in trying to do profiling on him. They've got experts who go back to every single part of his background, anything that he has ever done. People, they'll talk to people who knew him.
