Walling is a method of torture used by the CIA in which a person's neck is encircled by a collar, and is then used to slam the person against a wall. According to information gathered by the International Committee of the Red Cross from six detainees, "walling" meant "beating by use of a collar", in at least one instance against a concrete wall.[page needed]
Prompted to explain their interrogation techniques to the United States Department of Justice in 2005, the CIA provided a series of memos to the department's Office of Legal Counsel, one of which described "walling". The memo states that walling "involves the use of a flexible, false wall ... the interrogator pulls the individual forward and then quickly and firmly pushes the individual into the wall. It is the individual's shoulder blades that hit the wall. During this motion, the head and neck are supported with a rolled hood or towel".[page needed]
