Hmm,

There's plenty of evidence, and it indicates that aircraft were purposely piloted into the Twin Towers causing the conflagration that weakened the structure and precipitated the collapses. There's been more than one quality show on it including "Why The Towers Fell" which was on Nova. There have been a lot of 'theories' by internet know nothings which are as much theories as the one about the little men in the ground who make the grass grow. Interestingly, their are more theories out there than conclusions from this sort. Some of 'em have a lot of theories. It's the evidence for these theories that is lacking.

There's a distinction to be made between people, systems, presidents and presidents' relatives whom we may not like, and the facts of a situation. Being able to blame things on someone we are prepared to dislike doesn't suddenly make the facts change (for most of us, anyway).

But as my bud' Steven Colbert would no doubt say, being able to blame things on someone you suddenly discover may impact the 'truthiness'.

So go crazy, unnamed ones.
