I just want to say, as one of those filthy American types, that you always have the right to refuse anything, in any country for any reason.

You might be persecuted for it - but that right to say, “F-you I’m not talking” is always an option, it’s just that it tends to be more pain than most are willing to endure. Myself included, to be fair, but the right to “STFU” is pretty hard for them actually to force you to comply with if you decide not to talk.
