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".
Recently, British courts have rivalled their counterparts across the pond in competing for the most senseless judgment. The latest example came just yesterday, when three British judges said they could not rule on whether British officials were complicit in murdering Pakistani civilians in US drone strikes because that might embarrass our friends in America.
One of the books that detainees at Guantánamo Bay are 50 Shades of Grey, the international bestseller from the US writer EL James. Could it be that the US military authorities have decided that James' erotic thriller is actually pornographic (so-called "mummy porn") and therefore unsuitable for the camp's 155 detainees?
They know what they are doing to me is wrong and that's why they are scared. It is not me they are worried about, but they have some metaphorical sense that their mother or father is going to see what they are up to, and wonder what has become of them. Instead of being a brave soldier, they have been reduced to the rank of 'Scrotum Searcher Third Class', and they are told to beat up a defenceless and shackled prisoner with the help of five of their tough buddies.
I sent Shaker Aamer the sermon Reverend Nicholas Mercer delivered in October which denounces the UK's involvement in the tortuous and horrifying tactics used in the 'war on terror' and its continued denial of justice to those still subjected to those same practices. Shaker, clearly touched, wrote back almost immediately.
