Sir, I really can't speak to the timeline for this. This will be a decision, of course, for the committee and for Parliament, but maybe I can speak a bit about the threat environment and what we're seeing out there.
As I mentioned earlier, the threat environment is evolving, based on international events, incidents, technology, and the ability for people to exchange or receive information and learn from each other through the Internet.
Again, the number of people travelling abroad is still very real and a very serious concern for us, as is the number of people who could potentially fall off the radar once they've left. Then again, there's the work required to be able to work with security intelligence agencies, to have tripwires to determine whether they've come back in, and if so, what their intention is.
As you said, the advantage of having preventive measures allows us to be able to interdict and disrupt potential threats at an earlier period, and for public safety that's a big advantage, not only for our own public safety, but for that of our allies as well.
