Tom Kean and Lee Hamilton wrote an opinion piece last week in USAToday, trying to "temper" feelings surrounding the release of "the 28 pages."

Kean and Hamilton wrote, "The 28 pages have generated a lot of public speculation over the years and have been described as a 'smoking gun' implicating the Saudi government in the deadliest terrorist attack carried out on U.S. soil."

They go on to write, "What often gets lost in those theories is that the 28 pages were based almost entirely on raw, unvetted material that came to the FBI. That material was written up as possible leads for further investigation, and the 28 pages were a summary of some of those reports and leads as of the end of 2002 — all of them uninvestigated."
