This chapter completes the book’s coverage of the Aden case by charting the results and reactions that followed the use of the ‘five techniques’ there. It will be shown that not only was interrogation successful in producing intelligence, but that this intelligence was used to make improvements to the security situation in Aden. It will also be shown that interrogation was a valuable source of intelligence in relation to other sources. Investigations into allegations of brutality conducted by the International Committee of the Red Cross and Amnesty International are examined, as is the British Government’s response to these investigations, which took the form of the Bowen Inquiry into procedures for the arrest, interrogation and detention of suspects in Aden. These investigations led to increased concern for the welfare of prisoners amongst members of the governments of Aden and the UK.
