I think that you have to distinguish among the different environments. Obviously, in the airport environment, the consequences are extraordinary should individuals bring something onboard that could cause aircraft to go down.
It's not to say that we're cavalier about the possibility of narcotics entering our institutions, but it's not necessarily a fair comparison to talk about people bringing things on an airplane compared to into an institution.
Having said all of that, though, there are other security measures, as I said. There's enhanced reliability that all of our correctional officers have to pass in order to become correctional officers, and there's the ongoing supervision. It's not quite the same. We're not dealing with the unknown when we're dealing with visitors who are coming to our institutions.
