Yes and no. For the most part, I think some of the statements that have been made about the extent to which we need a pre-emptive mechanism discounts the extent to which our criminal law now actually encompasses, as terrorism offences, actions which are very far removed from acts of violence. There are mere acts of preparation that are now criminalized, so that broadens the scope of law enforcement activity and the prospects for arrest in conventional criminal prosecutions.
However, as Paul suggested and as was indicated before, I actually think there is a gap, a very narrow gap. In my paper I set out a series of hypotheticals in which this gap may arise. It's a very small gap, but I accept the argument made by law enforcement that such a gap exists.
