I agree you don't have to discuss your beliefs with me, so feel free to ignore this if you wish. But the problem I posed was not whether we would rather "see a thousand would-be terrorists held in preventive detention than than see one innocent individual blown to smithereens" - so would I. It is more whether we would rather see see let's say 100 innocents held in preventative detention in order to detain one actual would-be terrorist who is prepared to blow innocents to smithereens.

It is not an easy question and there are no simple answers, and probably no right answer either.
