One difference is that the allegations that he was a terrorist now appear to have been abandoned by the US government, which also seems to have given up denying the allegations of torture.

And there is no question whatsoever that he was held prisoner for seven years without being brought to trial.

There's no need to get all defensive. You can be absolutely certain that whatever was done to Binyam Mohammed during those seven long years, none of those responsible will suffer in any way for it.
