Five Britons are in jail in Saudi Arabia after confessing to planting bombs that killed westerners. However a sixth man, Ron Jones , claims he was tortured to confess to a bombing and can prove it. John Sweeney asks whether the real culprits are extremists loyal to Osama bin Laden , and whether the House of Saud is in a state of denial over the threat to the west and their own grip on power.
