No conspiracy theories here, but... "there is more than sufficient evidence" that the FBI,DOJ, et al, exhibited reprehensible lack of respect for the truth in OKBOMB.
Reprehensible...as in covering the crater with a 16-foot square of plywood (eight sheets) -- and then providing the visiting FEMA enginering team (who used FBI figures for their blast magnitude calculations) with information that the crater's diameter was 32 feet. (FWIW, the Fema team's own report states that they were kept 200 feet from the crime scene they were analyzing...)
The more some Freepers try to deflect it is just conspiracy theories the more convinced I am it was outright international terrorism with some domestic stooges used for patsies to take the fall.
