I'd need more than that to even bite a little.

Some problems I have with it:

1) I believe Nichols would have spilled this if it were true.

2) I think McVeigh would have boasted about the connection
("protect his family"?.....riiiiiiight. Little late for that wasn't it?)

3) Think of it from the terrorists point of view. What does McVeigh give them that they don't already have? Someone who could drive a standard?
