I can comment at a high level, representing IATA: we're completely opposed to racial and ethnic profiling.
Racial and ethnic profiling is not a security procedure. However, we do believe that behavioural profiling, whereby you take a look at how a person is reacting and interacting with their environment, has security value.
Certainly, there's the other aspect, too, and it goes to the discussion of how you leverage all this information we know about passengers. We do believe security needs to have a one-on-one interaction with each passenger. You just can't simply wave everybody through. We do think there's time to ask intelligent and intelligence-based questions of the passenger.
For instance, I came into the country last night and was asked the purpose of my being here. I said that I was going to testify for the first time in front of a committee of the House of Commons, and I was told that was very good.
By that same token, another passenger could come up and say he was going to the Delta Hotel. Perhaps in the next-generation checkpoint the questions would be about when he made his reservation and who made it, just to see if his story adds up. I think, as Mr. Sela said, that's what the Israelis try to do.
