Brian Whitaker writes in the Guardian:
"Imagine you are arrested and locked up, but you are not told why," one report by Amnesty International begins. "You are not allowed to make a telephone call or contact anyone outside the prison ... the only way to stop them is to sign a confession, which you eventually do. Then you are convicted on the basis of that "confession" after a summary trial that is held in secret. You have no access to a lawyer and you are not offered the opportunity to defend yourself."
There are indications that the Saudi government is trying to move towards reform, but those indications are largely on paper right now. It will only really count when there is hard evidence of real changes in how the criminal "justice" system there operates. That will, however, probably require some changes in many people's basic religious assumptions - and how easy will that be?
