My name is Mike Skrobica, and I am with the Air Transport Association of Canada. I'm responsible for the security file at ATAC and consequently I am hoping to answer on behalf of John.
With regard to the full-body scanners, we believe they are more appropriate for the Canadian situation than behavioural analysis. The behavioural analysis that has been suggested and trialled at CATSA is really Israel-lite, and even under the best of circumstances the sheer volume and number of flights far eclipses what you see in the very limited aviation market that is Israel. As a result, we believe a technological fix is appropriate. However, people electing not to go through the body scanner, or limiting it to people over 18 years of age, are definite loopholes and they need to be closed.
