Lacking Biolabs, Trailers Carried Case for War

"It would be easier to start all over with just a bucket," said Rod Barton, an Australian biological weapons expert and former member of the survey group.

The technical team's preliminary report was transmitted in the early hours of May 27, just before its members began boarding planes to return home. Within 24 hours, the CIA published its white paper, "Iraqi Mobile Biological Warfare Agent Production Plants," on its Web site.

After team members returned to Washington, they began work on a final report. At several points, members were questioned about revising their conclusions, according to sources knowledgeable about the conversations. The questioners generally wanted to know the same thing: Could the report's conclusions be softened, to leave open a possibility that the trailers might have been intended for weapons?

In the end, the final report -- 19 pages plus a 103-page appendix -- remained unequivocal in declaring the trailers unsuitable for weapons production.

"It was very assertive," said one weapons expert familiar with the report's contents.

Then, their mission completed, the team members returned to their jobs and watched as their work appeared to vanish.

"I went home and fully expected that our findings would be publicly stated," one member recalled. "It never happened. And I just had to live with it."
