Detention, once you're out, is not an answer either. I'm not saying that release on conditions is better than detention—it's worse than detention. They're both bad in the long term when you're not alleged to have engaged in criminality. There may be concerns about these people, but in the criminal sense, they've served their sentence. In the immigration sense, they're facing potential deportation; that's the issue, and that's why they're subject to controls. But I don't think the answer is to go back to jail.
Yes, we do have reviews. We go back to court and we try to get rid of the GPS. So far we haven't been successful. The court has maintained it because it was imposed in the first instance.
