I still am surprised with the prompt execution of McVeigh. Seems possible that someone, somewhere, wanted him gone permanently so he would not talk. Perhaps a couple prominent democrats, say a "husband" and "wife" who were up to their ears in scandal and dirt? Given the many illicit activities of this "couple" in other areas relevant to US national security; their predilection to sell out the country for election "contributions"; and the link between a prominent "pardonee" in 2000 and Saddam, Oil-for-Food, and the UN, perhaps there are some dots to be connected. John Doe #2 looks like he may still be operating here, and perhaps the "couple" in question knows him...or at least knows of him.
Perhaps if he were still around to answer a few more questions . .
