Dear Congressman:
I have read that you are about to start an investigation into the OKC bombing and that you intend to ignore implications and evidence that might involve links to international terrorism.
This is unwise in the extreme.
Most especially since it there is significant evidence that Terry Nichols had probable connections to Abu Sayf in the Philippines and recent translations of Iraq Documents show that Saddam's secret service was very involved with funding and advising Abu Sayf operations.
I urge you to widen the scope of you inquiry. Ignoring the obvious potential of this path to the truth can only cast doubt on the motives behind your investigation.
Sincerely:
I hope it helps. Washington DC is truly a puzzle palace. None of these guys seems to be able to grasp the obvious.
That's a good note and certainly worth the effort. Good job.
