If you like, I could perhaps begin and simply describe our role, going back to your first set of questions.
The service's role was in two parts. There was the validation issue with respect to accreditation: preventing persons from either entering the country or accessing sites. The second part, which dealt with threat assessments, reflects perfectly our mandate, which is to collect information, do some analysis, and provide advice to government, in this case, at all levels, but more particularly for the summits, to police and first responders, for them then to take whatever action they felt was necessary to deal with the threat.
Perhaps I could just delineate our role in terms of investigating and perhaps taking any action. The service's role is to bring to the table what it knows about issues, about persons, or about groups and tell law enforcement perhaps what's at issue, why it's happening, and perhaps even where and when, with some specificity, which would allow them to make tactical decisions. That's where our role finishes.
