all possibilities?
You have to base on comprehensive evidence.
Not just one of them.
As we all know, a result can be leaded by many different reasons.
All this conspiracy just based on a few evidence, that why we should reject it.
If you would bother at all to look at this from more than just your own personal point-of-view then you will see there is plenty of comprehensive evidence that says this could very well be the exact opposite of the official story we were given. Many demolition experts going on record to say that there was no way the buildings would have fallen in on themselves so cleanly from just being struck by planes. Many experts saying that the heat generated by burning fuel is nowhere near hot enough to melt the steel beams. Building 7 being "pulled" so quickly was a complete fabrication of the truth as, again, demolition experts said that setting up a demolition as clean as that one would have taken weeks to plan and prepare, yet we are to believe it was done in a matter of hours? Open your eyes man!
Actually this is not just "some" evidence that is here. There were way too many coincidences that happened that day or the days prior to 9/11. Mathematically it is impossible. If you think about it, this 'terrorist fight' hasn't yielded any results so far, but with it, they have justification for spying on the population.
