I understand the reintroduction did include some enhancements that were identified by the parliamentary committee which reviewed the Anti-terrorism Act on that. One of the logical arguments that follows is that the fact those powers were not extensively used, does show that the law enforcement and security intelligence community considered those to be quite serious and did not go out and “Go into the tool box” when they ought not to. It's one of the arguments that flows from that.
