Some of these horrors make agonising reading - but it is incorrect to say that they defy description. In the cold, expressionless language of the Senate report, even blunt, mechanical phrases can contain the key to understanding a world of pain. 'Rectal feeding' is one. 'Stress position' is another. Through reams of inert prose, an appalling picture of abuse is built up and solidified.
Just over seven months ago, activist, human rights champion and former Guantanamo detainee Moazzam Begg was arrested, arrested on the basis that during a trip to Syria he had facilitated terrorism (or so they said). Now two seasons later and just as his trial was set to begin he's been released with all charges levelled against him dropped.
The largest security services firm in the world, British company G4S, has accepted a £71million contract to run "base support operating services" at Guantánamo Bay... The UK government cannot turn a blind eye at a British company running a torture facility. The British public deserves an explanation.
It is undoubtedly true that there are some barbaric extremists who pervert the meaning of Islam - many of whom may now be associated with ISIS in Iraq and Syria. All the more reason, then, for us to identify our friends in the Islamic world, and treat them well. Why, then, did the British authorities treat my friend Nebeel Rajab, his wife, his 16-year-old son, and his 12-year-old daughter so badly?
Well, not exactly a slave, but a slave of the Guantánamo system. I'm talking about Shaker Aamer, the former UK resident who is still - still - marooned at the notorious US detention centre in the Caribbean almost exactly 12 years after being taken there during the height of George W Bush's frenzied and law-breaking "war on terror".
