I think with all criminal proceedings, there's a public interest component. I think we have to rely upon security officials to make informed decisions about, first, whether there's sufficient evidence and, second, whether it is in the public interest to prosecute.
I don't think that kind of “cut and dried” rule that everyone who comes back.... It might, frankly, be a misallocation of resources in some cases. In other cases, it may be very warranted. Again, I go back to the intelligence, to evidence consultation, and to the need, as the Air India commission urged, to strengthen our ability to do terrorism prosecutions when necessary, not in every case. Life isn't that simple.
