IIRC,McVeigh was an eyewitness to Waco.
He targeted OK since that’s where the ATF advance team’s HQ were...the Murrah BLDG.
True, but he's seems to have ignored the 'day care' that was also in the building. Bad, very bad move if you are trying to generate sympathy for a particular point of view.
I'm still convinced that the bombing plot was an 'agent provocateur' operation that got away from the FBI/ATF and had to be covered up right quickly. That was no two man job!
