No I do believe quite a few things..
I believe a number of different explanations may be true, but that only one of them is, and that I don't know which, - and also I believe that the question of how the towers came to fall down is a different question from who planned the attack, and finding out the answer to the one doesn't mean finding out the answer to the other.
And I believe that there are videos on youtube that are relevant to the first question, - and that there are a number of them, that show towers exploding but no plane impacts, and that they look more real to me than the same shots with plane impacts, and that this judgement of mine may be wrong, - and that maybe the impression of the plane sinking into the tower like a knife into butter and the fourway explosion is actually exactly how it should look.
And I think that people who haven't watched quite a few non news agency videos shouldn't comment on the value of the non-news sources.
