I listened to the Snodgres interview. Then I listened to a second one with John B. Wells on CTM.
In the second interview, Snodgres says that it is standard practice to have 2 different operations which don’t know about each other. IIRC, the Iraqis were at OKC and placed explosive charges inside the building (because a truck bomb could not take down the whole thing).
McVeigh was there for the truck bomb and was going to be the patsy who either got arrested or blown up by the truck bomb. Snodgres also says that there were 3 separate bombs placed inside the Murrah building but only one of them went off.
He said the FBI was there within minutes - before most of the local cops got there - and that one of the FBI missions was to retrieve the 2 bombs that didn’t go off so that investigators would not find them. He also says that a local cop who was first on the scene saw things and was later Arkancided for it along with a few other people who had copies of the records he kept.
