Because I don't make any conclusions just because I acknowledge a piece of evidence. Truthers claim that our government carried out the attack. Which may or may not be true, but having evidence of a controlled demolition of the outlying building alone is not enough to state that in either direction.
I also don't think it matters. The government used the event to seize more power and control either way. The government is the enemy, whether or not you can pin every crime on them or not.
