One area that is questionable in which we could redeploy resources, both funding and personnel, is the non-passenger screening that we have at Canadian airports. As the testimony of John McKenna indicated, Israel and the United States don't have it. That doesn't stop the Americans from giving us advice that we don't screen a large enough sample of our non-passengers. Those non-passengers include pilots and other personnel who could be in a unique circumstance to cause a terrorist incident, but the experience is that they have not.
One of the things we need, as in any system, is to review the results of our experience. Are they finding threat items? Are they stopping terrorist incidents? If the answer after five, six, or seven years for non-passenger screening is no, then perhaps we should ask some questions. Is this the right way to deploy our capital and human resources?
