Well, DMcG, I don't actually have to discuss my beliefs with you at all but, since you asked so nicely, my preference is of the 'convict the guilty and release the innocent, having taken all available means, short of torture, to establish that guilt or innocence' kind.

But, if that means holdng someone until all of the facts are established, so be it. People who embark on a course of extremism need to be made to understand that they will be called to face responsibility for their own actions, however unpleasant that may be.

I'd rather see a thousand would-be terrorists held in preventive detention than than see one innocent individual blown to smithereens. If you can't do the time, don't do the crime. And if you don't want to be treated like a terrorist suspect, don't behave like one. Simple.

And you know what? I'd bet my pension that the majority of British citizens, including Muslims (most of whom, including my neighbours, are good and civilised people), feel very much the same.
