Colin Powell does not need more humiliation. But yesterday a London jury brought down another section of the case he made for war - that Iraq and Osama bin Laden were supporting and directing terrorist poison cells throughout Europe, including a London ricin ring. Yesterday's verdicts on five defendants ... make clear there was no ricin ring. Nor did the ricin ring" make or have ricin. Not that the government shared that news with us. The public record for the past three fear-inducing years has been that ricin was found in the Wood Green flat occupied by some of yesterday's acquitted defendants. It wasn't. [Found there] were the internal documents of the supposed al-Qaida cell planning the "big one" in Britain. But the recipes were untested and unoriginal, borrowed from US sources. Moreover, ricin is not a weapon of mass destruction. It is a poison which has only ever been used for one-on-one killings. All the information roads led west, not to Kabul but to California and the US midwest. The recipes for ricin now seen on the internet were invented 20 years ago by survivalist Kurt Saxon. The chemical lists found in London were an exact copy of pages on an internet site in Palo Alto, California. But it seems this information was not shared with the then home secretary, David Blunkett, who was still whipping up fear two weeks later. The most ironic twist was an attempt to introduce an "al- Qaida manual" into the case. To show that the Jihad manual was written in the 1980s ... was easy. The ricin recipe it contained was a direct translation from a 1988 US book called the Poisoner's Handbook. We have all been victims of this mass deception.
