One of the blackest marks on the record of the Obama administration is the failure to prosecute GW Bush and his Republican minions for crimes against humanity. It is a violation of US law and destroys US credibility internationally on the subject of human rights. But we can still hope that someone in the international community might do for us what we should be doing for ourselves.

US [sic] security chiefs have condemned former President George W Bush’s defence of torture yesterday, and disputed his claim that information obtained by subjecting prisoners to simulated drowning or ‘waterboarding’ had scuttled Al Qaeda plots to blow up Canary Wharf and Heathrow airport.

Negating the claims of Bush, Lord MacDonald, the former Director of Public Prosecutions, said: "These stories about waterboarding thwarting attacks on Canary Wharf and Heathrow – I’ve never seen anything to substantiate these claims. These claims are to be treated with a great deal of scepticism."

The Daily Mail quoted a Downing Street spokesman, as saying, "We stand firmly against torture and the cruel, inhumane or degrading treatment or punishment. We don’t condone it or ask others to do it on our behalf."

Meanwhile, lawyers have warned that by having sanctioned the controversial interrogation technique, he could now be arrested for breaking international law if he travels abroad.

"Ignorance of the law is no defence. There are countries where proceedings might be instituted against him," human rights lawyer Geoffrey Robertson said.

Bush made this comments during an interview while launching his memoir "Decision Points", admitting that he gave the CIA the green light to waterboard Khalid Sheikh Mohammed, the mastermind of the 9/11 attacks. He added that a team of U.S. lawyers had said the practice was not illegal.

However, his claims about waterboarding were dismissed by a series of senior officials familiar with counter-terrorism activities at the time, saying that the President was exaggerating.

Kim Howells, who was chairman of the Commons intelligence and security committee, said: "I doubt torture actually produced information which was instrumental in preventing those plots coming to fruition. I’m not convinced of that."… [emphasis added]
