The cabinet secretary is right; I welcome the new offence. It is an important step forward and it would correct many of the issues. However, as Liam Kerr put it, when someone goes over the prison wall, we do not wait for them to rob a bank before we arrest them. We arrest them once they have gone over the wall. If someone cuts off their tag, we should not wait—their doing so should, in itself, be a ground for arresting that person.
