So we just simply are, generally, as a country—most New Zealanders—reasonably naive about the fact that we might have at any time 30 to 40 people who are giving the security agencies a great deal of concern. There could also be several hundred people that they are concerned with, because things have changed and we need to be able to adapt to them. I think one of the things that we can sometimes do when we're bringing about law changes like this that we're talking about, and those that might be needed around the ability to remove from New Zealand people who are legally here as refugees or as protected persons, should they become a national security threat, is that we need to perhaps put limitations, time limits on some of these provisions. Because society changes, rules change, the ability to deal with things change, and we need to be able to adapt.
