Thank you for your questions. Let me answer them in order.
To the first question, there is a comprehensive air surveillance and security plan that is put in place. My command is working in partnership with NORAD, which is a binational command—not a U.S. command—that is responsible for aerospace surveillance and control of North America. It is clearly the appropriate agency with the expertise necessary to deal with a complex air security environment. In this case we work with the RCMP because many of the foreseeable problems are really policing problems, not military problems, but we have a long history of cooperating together to ensure that we keep Canadians safe and secure.
There's a number of different layered approaches to surveillance, involving a number of different types of surveillance assets: space-based, ground-based, and air-based. There is a range of response options that are being modelled. I don't wish actually to comment on the specific instruments we will deploy during the games, because I think that's not really helpful to our ability to control the whole environment. I will say that the Vancouver environment is a particularly challenging one for a ground-based missile system to have effect in very many scenarios. We're taking that into consideration as we look at the comprehensive air security plan during the games.
