Saudis have not been involved in rendition process. They do torture mujahideen but were not officially involved in the rendition process unlike countries like libya, syria, morroco, pakistan just to name a few. what happens is mujahideen were captured and then taken to ghost prisons in these countries and then tortured. The americans did not want to get their hands dirty so they like outsourced the torture. This is all well documented.
