This may very well become a disaster for the Brits.
If they're coaching the sailors to give accounts of tough conditions, and it isn't the truth, it's bound to sooner or later come out.
It's obvious from the video clip that they were relaxed, at least at that time. The torture must've started after that video was made.
But it is doubtful IMO.
The Brits should've just have let this one drop. Now this issue will stay around for a long time, even make the PR victory for Iran bigger.
