There are many problems with the official story of the bombing. Let's start with McVeigh's whereabouts on April 17.
McVeigh had been filmed by a security camera at a nearby McDonald's 24 minutes before the time stamped on the truck rental agreement, wearing clothes that did not match either of the men seen at Elliott's.
There is no plausible explanation of how he traveled the mile and a quarter from McDonald's to the rental agency, carless and alone as he claims, without getting soaked in the rain.
The three people interviewed agreed John Does 1 and 2 were dry. According to Stephen Jones, who has seen the interview transcripts, it took 44 days for the FBI to convince the car rental agency owner that John Doe 1 was Timothy McVeigh. And in the end they did not dare put him on the witness stand, for fear of what might happen under cross-examination.
There is also an unanswered question with regard to the truck, namely what was the Army doing with a Ryder Truck just before the Murrah blast?
From CNN Transcripts:
"...here's now what we are starting to learn about the succession, or what someone obviously hoped would be a succession of explosions. The first bomb that was in the federal building did go off ... the second explosive was found and defused. The third explosive that was found and they are working on it right now ... both the second and third explosives, if you can imagine this, were larger than the first. ... It is just incredible to think that there was that much heavy artillery that was somehow moved into the downtown Oklahoma City federal building."
"...this is the work of a sophisticated group, this is a very sophisticated device, and it has to have been done by an explosives expert."
There's more. There are recordings and seismic data which show multiple "booms" when the official report just said one. There are plenty of video clips on google where you can see MSNBC, CNN, and FOX announcing bombs #2 and #3 were found and removed.
