Although it seems to be forgotten, the first victim of pre-war intelligence is dead, supposedly by his own hand.
From Wikpedia:
Dr. David Christopher Kelly CMG (May 17, 1944 - July 17, 2003) was an employee of the British Ministry of Defence (MoD), an expert in biological warfare, and a former United Nations weapons inspector in Iraq. His talk with a journalist about the British government's dossier on weapons of mass destruction (WMD) in Iraq inadvertently caused a major political scandal, and he was found dead days after appearing before a Parliamentary committee investigating it. The Hutton Inquiry, a public inquiry into his death, found that he had committed suicide. Read it all here: http://en.wikipedia.org/wiki/David_Kelly#Involvement_with_the_WMD_dossier
Kelly's experience of weapons inspections led to him being asked to proofread sections of the [UK's]draft dossier on the history of inspections. Kelly was unhappy with some of the claims in the draft, particularly a claim, originating from August 2002, that Iraq was capable of firing battlefield biological and chemical weapons within 45 minutes of an order to use them.
On May 22, 2003, at the Charing Cross hotel in London, Kelly met with Andrew Gilligan, a BBC journalist who had spent the war in Baghdad. Kelly told Gilligan of his concerns over the 45-minute claim and ascribed its inclusion in the dossier to Alastair Campbell, the director of communications for Prime Minister Tony Blair. Gilligan broadcast his report on May 29, in which he said that the 45-minute claim had been placed in the dossier by the government, even though it knew the claim was dubious.
The story caused a political storm, with the government denying any involvement in the intelligence content of the dossier. The government pressed the BBC to reveal the name of the source because it knew that any source who was not a member of the Joint Intelligence Committee would not have known who had a role in the preparation of the dossier.
Kelly was interviewed twice by his employers, who concluded that they could not be sure he was Gilligan's only source. Eventually they took the decision to publicise the fact that someone had come forward who might be the source. The announcement contained sufficient clues for alert journalists to guess Kelly's identity and the Ministry of Defence confirmed the name when it was put to them.
When he appeared before the Foreign Affairs Select Committee on July 15, Kelly appeared to be under severe stress. Two days later, he was found dead in woods nearby his home.
