This weeked will mark the 10th anniversary of the 11 September 2001 terrorist attacks. Despite the intervening decade, the states threatened by terrorism are still puzzling out the right balance between the powers of security services and the rights of suspected terrorists to due process.

Although terrorism is now mercifully low on the public agenda, the effects of 9/11 are still being felt across the legal system. The UK is soon to open an independent inquiry into the improper treatment of detainees by security services following the terrorist attacks. As things stand, the UK’s major human rights groups are boycotting the inquiry for fear that the Government will be able to suppress evidence.
