It is now well documented that the Blair government was colluding at the highest levels in the global system for the rendition, detention and interrogation of terror suspects, at the same time as repeatedly denying any involvement. This paper seeks to explain why the UK so confidently maintained its position of denial. The main argument is that involvement in the global rendition system was facilitated and protected by an architecture of impunity. That is to say that the global rendition system deliberately consisted of a set of practices that were designed to ensure impunity for those agents involved at various levels, particularly Western governments and their intelligence agencies. Furthermore, if aspects of a state’s involvement were exposed, the architecture of impunity was sufficiently robust that the state could control the level of exposure. For example, the state could allow the light to be shone on certain aspects but could keep others very much in the dark. The state could also take specific actions to mitigate the effects, for example by withholding key information, destroying evidence, or by deflecting attention. Finally, where state involvement was exposed, again because the architecture of impunity was so robust, the authorities were in a strong position to seriously hamstring or avert investigations into wrongdoing. We conclude by offering some reflections on what this tells us about the challenges of holding governments to account for human rights violations of this nature, especially where they arise through a transnational network of state violence/crime
