London (CNN)UK lawmakers have delivered a stark assessment of the conduct of British spies and their US allies in the decade after 9/11, concluding it was "inexcusable" that UK security officials participated in or tolerated the freewheeling counter-terror practices of the time, like detainee abuse or extraordinary rendition.
UK officials tolerated 'inexcusable' abuse of US detainees, report finds
The exhaustive report, the product of 30,000 hours of work and 50 hours of oral evidence to Parliament's Intelligence and Security Committee (ISC), focused on a still-uncomfortable yet distant counter-terrorism struggle against al Qaeda a decade ago. It largely exonerated UK agencies in the direct abuse of terror suspects.
It concluded UK officials had never engaged in physical abuse of detainees between 2001 and 2010, had only been "involved" in it twice, and witnessed it firsthand 13 times. Only nine cases of UK officials delivering "verbal abuse" to detainees were reported over the nine-year period.
But it noted there were 127 incidents in which UK officials were made aware of mistreatment by foreign services, and that in 232 cases UK officials continued to supply intelligence or questions to be asked in interrogation by foreign allies, despite being aware of detainee mistreatment.
"It is easy to criticize with the benefit of hindsight," said Dominic Grieve, a member of Parliament and the chairman of the ISC, in a statement accompanying the report.
"We wish to be absolutely clear that we do not seek to blame individual officers acting under immense pressure. Our findings must be viewed in the context in which the events took place. The pace of work after 9/11, both in Afghanistan and London, was frenetic: We do not underestimate the pressure that the agencies experienced whilst dealing with the imperative to protect the UK and prevent another attack on the scale of 9/11."
"With that said, more could have been done at an agency and ministerial level to seek to influence US behavior. More could also have been done to distance themselves from mistreatment of detainees.
The intense scrutiny and at times scolding language of the report contrasts with rhetoric in the White House over detainee abuse. President Donald Trump, as a candidate, declared he believes "torture works". US officials deny that is the case, or that US officials abuse detainees.
The current director of the CIA, Gina Haspel, has said she would not restart the controversial "enhanced interrogation" program. But she has faced questions over her role as supervisor of a CIA "black site" in Thailand where harsh interrogations took place, and had a role in the destruction of CIA interrogation tapes.
The report emphasized the distance between US hardline political rhetoric and European intelligence practice, many issues of which remain current as the US and its European allies struggle to remove foreign ISIS fighters from custody in northern Syria so they can be tried in Western courts.
A UK security source said after the report's release: "Today, we do things differently. We have learned the lessons of those difficult post-9/11 years and structures have matured, both in SIS [MI6, Britain's foreign intelligence service] and across government."
While many of its conclusions were historical, the ISC report did call on the UK government to spell out within three months its current policy over UK airspace and territory being used for any possible American rendition flights, saying it was "astonishing" how little progress had been made in this area.
