That's the reason for the sunset clause. When it expires, you evaluate the evidence you have in terms of the dangers the changes seek. I think it's no coincidence that at the same time as we are doing this exercise--and we should do it thoroughly, by looking at the evidence we have of abuses on one side and at the lack of these provisions.... Particularly since 2007, when these provisions were sunsetted and so haven't been in force, prosecutions for terrorism acts have occurred. So it's not as though the police have been unable to act. On the contrary, I think they have been able to act.
It's no surprise that now, in the U.K., they are re-evaluating whether the strong and difficult and dangerous tools, such as control orders, ought not be re-evaluated.
The idea of stepping back, saying that this was not necessary, is no longer necessary, and is not the best way to go--that it's better to invest in better intelligence than to simply give more powers--I think may be a better assessment at this stage.
