They may be, but Miranda wasn't. If you want to be clever, at least bother to get a basic understanding of how Schedule 7 works. Specifically, examination under these provisions is
N*O*T based on"suspicion of commission of an offence", but to ascertain if the person examined is or has been concerned in terrorism. It is a major distinction that you need to grasp.
The whole point of that is so that someone detained for examination cannot later argue that there were no grounds for suspecting them, and thus that the process was unlawful.
Now, if you wanted to contend that surely that's a mechanism for purely arbitrary stops, or else could be used to target (say) an ethnic group, well, er, yes, and indeed I believe there are a number of cases heading for Europe on just that point, but I'm simply talking about the situation as it is.
Quote: DaveO " The investigation proceeds with them on remand or bailed and either goes to court or is terminated with the charges dropped. '"
And how do you bail someone who is not actually in the UK, then? But as you are utterly confusing this situation with that of a person arrested under UK domestic law, I won't add to your woes. Come back when you've mugged up, if you like.
