Confessions of British Sailors

The "confessions" from British Naval officers that they had indeed entered Iranian waters leave me confused.  Are the sailors being coerced by threat of torture or death?  Shouldn't they have the courage and training to call such a bluff?  Or did the Iranians somehow convince them that they were in fact mistaken and had entered their territory? Or is there a third explanation, that they actually did fuck up and stray across the border.

Which is it /pol/?
