Thank you, Chair.
I enjoyed this discussion. It's interesting.
I wanted to ask a question about threat assessment and how you arrive at threat assessment.
Recently I was listening to a Freakonomics program, and they had brought on four experts on terrorism. And the question was, if you were invited to President Obama's recent meeting, which I think our public safety minister went to, what advice would you give the President on threat assessment? And they talked about the efficiency of terrorism, that you get a lot of bang for the buck, for want of a better of term, and the inverse, which is that we pour a lot of resources into coping with the threat of terrorism with sometimes questionable results in the end, and so it's a reverse.
Interestingly, they made the same comment that you made, which is toxic chemicals or the spread of toxic chemicals is probably the most significant terrorist threat. Their argument was it's really more good luck than good management and maybe just the stupidity of terrorists to not realize that this is actually the most significant threat to a large population.
Mr. Chisu's talking about the Pan Am Games where there will be a large gathering of people and so a smart terrorist wanting to do really serious damage would use an event such as that and would use chemicals rather than other forms of terror.
I just would be interested in your thoughts on whether that is in fact an appropriate threat analysis, that it is, if you will, the chief of your worries.
