Give it up...
Some people seem to have a need for conspiracy theories- I have never understood that... The fact is McVeigh and some friends committed an act of mass murder- that is IT... there must be some part of humans that needs to believe that a small number of people cant do something so horrific - ie one man couldnt kill kennedy... the fact is sometimes a very few can kill very many...
The conspiracy theorists are no better than the bigfoot enthusiasts and the UFO nuts...
In short, grow up and get a life
