that the four FBI agents shot at Waco were killed by the Dravidians (never mind that their previous asignment was to guard Gov. Clinton)

I believe no FBI agents died at Waco. The original raid, with the shot agents, was by the BTF. I have no idea what the assignments of the dead agents was.

that it's perfeclty understable that the 2nd tower hit (with the fuel tank fireball outside the building) was the first to fall.

Actually, it makes perfect sense. The second tower was hit much lower. The structural members being weakened by the heat of the fire carried at least twice as much weight as those in the other tower. Of course it collapsed in less time.

I think you overlooked something.
