I'm going to jump back in because there's a large panel.
I heard some names—Hong Kong, Heathrow—and I can appreciate that there's the IATA, but there's a lot of variance between screening. I've gone places where I've walked in with my shoes. There are others where I have to go in the body scanner. Recently I was screened when entering the airport and then, before the beautiful boutiques and concourse, I was screened again. There's a lot of variance.
This is a two-part question, and then I'll be out of time. What is the need to change our screening procedure, and then, is there a regime that has it right that we should model ourselves after?
