I'm just going to pick up from that, if I may. I raised this the other day with some of our other witnesses. We are always in this destructive situation wherein old technologies are bygone very quickly because of the destructive minds that are out there.
Mr. McKenna, in your report you asked why we can't use a modern detection technology that will reduce the number of stages and the time and personnel required to process passengers. So you're not thinking that the behavioural identification is going to be part of this. In your comment on the full-body scanners you say they're an improvement, but they're not the most efficient.
Where are we going to go among these modern technologies? What else are you looking at?
