That is the crux of the problem. The Justice Department and the NIS have acknowledged for years that all information in the Weinberger pre-sentencing letter has been declassified. But they refuse to declassify the letter itself, or let his lawyers, who have the necessary clearances, to see the letter. It should be declassified, then we can see what he did, and what he didn't. Particularly significant given the fact that the damage assessment, which Weinberger relied on, was written by Aldrich Ames. Who obviously would have motivation to cast blame on someone aside from himself. Better to do it now when, if he was sentenced based on Ames crimes, he could be released after serving a reasonable sentence than waiting 30 years and finding out he was sentenced based on faulty information.
There's another one who should have been treated to a short rope and a long drop.
