I remember at the time that the John Birch Society did a very deep investigation into McVeigh's association with a kind of separatist group at their "Elohim City" base of operations. And the analysis of the blast damage by a military demolition expert. Plenty of hard evidence. (But make no mistake about it, an ANFO [ammonium nitrate & fuel oil] bomb is no joke. Having inside help was icing on the cake to assure the scenario success.)
