The "government"? Where in the world did that come from?
I'm thinking the more likely scenario that the Clinton administration would have been wanting to cover up was a complex operation in place. Would have been extremely difficult to explain how these two local yodels would know how to do something right out of a "Mission Impossible" episode.
If there is anything to hide, and clearly there is otherwise they would not have 'washed' the tapes, then I would think that would be it.
Please address the logic of the pre-placed small charge theory:
Why only put a few small charges on the same side as the bomb truck instead of putting them throughout the whole building to bring it all down, thereby killing more people and doing a better job of destroying the evidence?
