I think that balance between public safety and fundamental liberties and human rights is really at the heart of all this. Perhaps I can quote Lord Hoffman, who is one of the judges in the Belmarsh detainees case. In his judgment, he said:
I said that the power of detention is at present confined to foreigners and I would not like to give the impression that all that was necessary was to extend the power to United Kingdom citizens as well. In my opinion, such a power in any form is not compatible with our constitution. The real threat to the life of the nation, in the sense of a people living in accordance with its traditional laws and political values, comes not from terrorism but from laws such as these.
That was part of his judgment.
It seems to me that the starting point one must have in a democratic society is one must have good intelligence. In fact, if you lock up everyone who's on your intelligence radar or place them under control orders, house arrests, that wouldn't have prevented either the atrocity that took place in Madrid, or indeed the London bombings that took place on 7/7 in the London tube. They happened because intelligence either was not there or had not been properly applied.
So you find that locking people up may enable the politicians—and I know I'm talking to politicians—to look as if they are protecting us, but the reality is that for the next set of bombers, if they are not on their radar, then at best it's going to be a cosmetic measure to appease public fear and probably not much else.
Secondly, when people are on your radar, assessments and information of the intelligence services, it seems to me, need to be turned into evidence so that the suspected perpetrators can be arrested, tried, and convicted before the courts in open and fair trials. And that in fact is being done in the U.K. on a very big scale now. So far, it's causing a whole lot of other problems in terms of a pileup of cases in certain courts in London and overworked police officers, but that is, it seems to me, the way to go. The starting point for it all is having good intelligence.
