'Reflection not retribution'
Updated on 17 April 2009
Civil rights campaigners are disappointed with Barack Obama's decision not to prosecute any CIA operatives over the tactics used under George Bush.
The president has called it "a time for reflection, not retribution".
Details of the harsh interrogation techniques used under the Bush administration emerged from four secret legal memos released by the White House last night.
They revealed that prisoners' heads were slammed into walls, they were doused in water, confined in small boxes and deprived of sleep for days on end.
