Prior to 9/11, Britain became complicit in America's War on Terror, and the worst of its crimes, including renouncing the rule of law, due process, and judicial fairness in persecuting innocent people, subjecting them to barbaric torture, other abuses, and long internments.
Muslims were targets of choice for their faith, ethnicity, prominence, activism, and at times charity. They've been singled out, hunted down, rounded up, held in detention, kept in isolation, denied bail, restricted in their right to counsel, tried on secret evidence and bogus charges, convicted in sham proceedings, then incarcerated as political prisoners for practicing Islam at the wrong time in America and Britain.
Targets were kidnapped, illegally detained, then extrajudicially disappeared to black sites, called extraordinary or irregular rendition, or the practice of forcibly transferring someone from one nation to another. The term is undefined in law.
Fabricating Terrorism II covers 29 case studies "mostly detailing the experiences of British citizens and British residents granted asylum (showing how they) passed through a subterranean system of kidnappings, ghosted to 'black sites,' suffering abuse and torture" to extract information and confessions known to be unreliable and false." In addition, no one was charged with terrorism or other crimes. UK authorities knew it before their rendition, yet allowed it and their torture to happen.
