The NIE report is prepared by a group that lobbies are not allowed to legally influence. Our bureaucracy is likely less "political" than the elected bodies who it seems are now succumbing to the pressure of lobbying orgs to review the report. Also, our intelligence agencies prepare their own reports, and it is know that it is becoming common practice on the Hill to allow lobbies to draft and submit various items including legislation through the Reps and Senators they sponsor. In addition, the NIE findings are supported by those of the IAEA which has already said the American elected institutions are attempting to mislead our public again as they did in Iraq.
