Guantanamo Bay operating procedures

 The "Standard Operating Procedures for Camp Delta", the US Army manual for soldiers dealing with prisoners at Camp Delta, was released on Wikileaks in 2007. Human rights groups were concerned to discover that according to official guidelines, prisoners could be denied access to the Red Cross for up to four weeks. It also showed that inmates could earn "special rewards" for good behaviour and cooperation - and that one such "reward" was a roll of toilet paper.
 Scientology

In 2008, Wikileaks published "the collected secret 'bibles' of Scientology", including some of internal workings and strange practices of the controversial Church. It showed that there were eight "levels" of "Operating Thetans", with Level Eight being the highest, that Scientologists can aspire to. It also instructed adherents to carry out difficult-to-understand "drills" including: "Find a tight packed crowd of people. Write it as a crowd and then as individuals until you have a cognition. Note it down." The drills were written by the Church founder L Ron Hubbard himself. Lawyers for the Church of Scientology attempted to force Wikileaks to take the information down, calling it the "Advanced Technology of the Scientology religion", but the site refused.
