Thank you for this well researched article, Richard. So the identity of the protected asset seems to be of greater importance to the FBI than of the public knowing the truth.

It is clear from the court proceedings that the trials are framed in such a way as to eliminate the possibility of any suspects other than McVeigh and Nichols.

If the FBI had an intelligence asset on the inside of the OKC bomb plot, why didn't they intervene? What matter of state interest is greater than innocent lives?
