 Again, I think it's too early to say that. We have one shooter tentatively identified, but we're not stopping there. We're following up on a lot of information. It will be some time until we can conclusively say or answer that question. How long do you think that gunman is hiding up there? We saw the snipers up there, you know, as the crowds were kind of mulling in. It looked like he was going to check everyone out. So how long has that guy been up there?
