9/11 Problem Still Uncorrected?

In a book I'm currently reading about the CIA, "Legacy of Ashes,"

NY Times Reporter Tim Weiner draws a parallel between the Kennedy assassination and the 9/11 attacks in that in the former case, FBI, CIA, INS and other government agencies all had files on Lee Harvey Oswald and weren't sharing their intelligence. In the latter, as we all know, these same agencies failed to share intelligence, and this failure very possibly thwarted America's chances of averting the attacks.

Last night I attended an invitation-only event on 9/11 at Richard Stockton College, featuring former Governor and 9/11 Commission Co-Chair Thomas Kean,who stated that the new Director of National Intelligence falls short of the Commission's recommendations. Specifically, Kean said, the new director lacks budgetary power over US intelligence. The gist of Governor Kean's remarks is that America still falls short of the intelligence sharing capabilities that could perhaps prevent another such tragedy.
