Obviously I can't comment on specific operational activities that occurred, but I can speak a bit more generally about how we do our investigations.
We have a number of authorities under the CSIS Act. The CSIS Act permits us to investigate, to the extent that it's strictly necessary, threats to the security of Canada. We use a number of methods for doing that, including interviews, surveillance and things like that. We can apply for Federal Court warrants for intrusive techniques. To do a search of a vehicle, for example, would require a Federal Court warrant, and you'd have to be able to demonstrate that there are reasonable grounds to believe that there is a threat in order to get that warrant. That's in the CSIS Act.
The practical application is that sometimes we're in a position to provide useful intelligence and sometimes we're not.
