The memo described ten techniques which the interrogators wanted to use: "(1) attention grasp, (2) walling, (3) facial hold, (4) facial slap (insult slap), (5) cramped confinement, (6) wall standing, (7) stress positions, (8) sleep deprivation, (9) insects placed in a confinement box, and (10) the waterboard." Many of the techniques were, until then, generally considered illegal. Many other techniques developed by the CIA were held to constitute inhumane and degrading treatment and torture under the United Nations Convention against Torture and Article 3 of the European Convention on Human Rights.
