I can accept that when you're talking especially about young people—it's the same in the criminal concern—who are going around robbing buildings and you want them to stay at home, it might be useful if there's a curfew on them, to have a GPS, but again, for a very fixed period of time, not long. If it's over a long period of time, it becomes oppressive.
