As Mr. Piragoff pointed out to me, to have the tools to be able to have some retrospective investigation into past activity is important to preventing future activity. I don't buy into the theory or possibility that somebody, just because they have been involved with prior terrorist activity, won't do anything in the future. I don't subscribe to that. Yes, you can be called before an investigative hearing regarding what you have done in the past in terms of facilitating or participating in terrorist activity. It seems to me that's a part of what we're trying to do: break up any possible future terrorist activity. I think this is only reasonable.
