Carry_Okie, thanks for the ping from another thread.
I am looking for a plausible theory regarding the OKC bombing, that would explain the admission of guilt and silence on the particulars by McVeigh. He just doesn't fit the role of a Middle Eastern patsy.
One can assume that there was a steady stream of warnings about the WTC bombing, since the first attempt. Unless there was a warning that had pointed to the method of attack and the date, what could the FBI possibly do, short of closing down the WTC for good?
