I don't think we have a problem with preventing serious criminals from coming here. None of the examples, at least of those I've seen that the minister has given, involves somebody who got in who shouldn't have gotten in. They're all of people who have committed offences after they got here.
I think the tools are already there. Also, they're improving the use of biometrics. It's going to be much harder for a person—somebody who has been deported, let's say—to adopt a false name or false ID and come back, because the minister is bringing in some other proposals to make this more effective.
I've already commented about this enough. I have made the point that you can do triage. You can have the officers impose conditions on the less serious offences, so that you save the more serious ones to go to full hearings.
