At the time the audit was done, we had already dealt with part of the solution to that problem. That is to create a feedback loop just in airports—that's the only place where we were ahead of the game—that would allow the people at the primary inspection line, the people at secondary, and management to measure performance from that perspective: the quality of the referral to secondary.
We discovered that the system was not used properly. That's a question of training and guidelines that had to be put in place. But we're okay at the moment there.
There are other places where we need that feedback loop to be established, and we will need a bit of time to get all of the benefit that could be gotten out of that feedback. But we are doing it.
