The Senate report did offer a crucial insight, however: the first complete list of prisoners held in the CIA's black sites. 119 names, each with a date of custody (redacted) and a record of how many days they were held (also partly redacted).
In the days after the publication of the Senate report, we set to work reconstructing this list to reveal the hidden dates. Figuring out a date often meant that we could match it to a flight record; matching to a flight record meant that we could determine where a prisoner was brought from or sent to. As we cross-correlated thousands of data points -- from declassified government documents, footnotes in the Senate report, aviation data, records of corporate outsourcing of rendition flights, legal cases, media reporting and NGO investigations -- the contours of the CIA's programme of secret detention and torture began to emerge more clearly. Rather than just understanding certain individual histories, we could begin to discern the entire scope of the programme's development.
More than four years later, we're publishing the results of our investigation in a 400-page report entitled CIA Torture Unredacted. It is the first time that the entirety of the CIA's detention programme has been systematically revealed.
When the Senate Committee released their report, fewer than half the names on the list of prisoners were known. We reported in 2015 that only 36 of those held by the CIA had been taken on to Guantanamo Bay, while the fate of many of the others remained a mystery. Seized in secret, held in secret, they were then disposed of in secret -- some back to their homes, some into continued custody in other countries, again often in secret
Since then, we've been able to establish the histories -- at least to some extent -- of around 100 prisoners. We've traced over 60 operations to transport them to and from prison sites. We've uncovered who was held in Afghanistan, and revealed more fully than before who was sent to the European black sites, in Poland, Romania and Lithuania. We've also brought to light further details of how deeply implicated the UK was in the overall running of the CIA's torture network.
