Re: "We take a rather different view over here"
"Um, the reference there seems to be to Hussain, whose evidence was reported as having been affected by the risk of prejudicing his US appeal."
But the judge should, and almost certainly is, cogniscant of the fact that Hussain is appealing the judgment, and so doesn't want to be caught in a perjury trap. If POTUS can use that argument, surely Hussain can.
I guess the point is that the more you discuss a case, the more likely it is to say something that, possibly accidentally, contradicts something said earlier, especially when discussing recollections of past events. "I don't remember" and "I do remember" appear contradictory, but are not if spoken at different times. But a US court will throw you in jail for that sort of flip flopping, especially if you are a foreigner and have a name like Hussain. (Of course, the US legal system is definitely not corrupt, xenophobic or racist.) Hence shutting up in the US system is an absolute must.
