I know.
You don't want objectifiable facts - you want fantasy, spin, rumor and tantalizing tales of intrigue!
Sorry, real life is pretty dull; MOST accidents and events are just that - accidents and failures of systems man has put together with the lowest bidder ...
Throw in corruption. Not to single out Oklahoma (all states have corruption) but I've long believed that razing the building so quickly was more likely to cover up for shoddy construction materials, etc. I do remember Oklahoma-related corruption and federal construction projects preceding the construction of the building. Mostly on the interstate highway system in the 1960s I believe.
But the idea that it was just McVeigh and Nichols is nuts. I've long asked why so many were willing to let the others go. Why weren't people who saw McVeigh that morning allowed to testify at his trail? Ans: because they saw him with others. The witnesses were just ordinary Americans who happened to be in the area.
