His continued incarceration in Guantánamo Bay is – by any standards of justice and decency – a stinking scandal. I suspect that British and American authorities fear that Mr Aamer, a highly articulate man, might well embarrass them upon his release. I hope he does. I have also heard suggestions that the United States would prefer to send him back to Saudi Arabia – but that is surely unthinkable because he would risk facing fresh maltreatment, illegal imprisonment and torture.
