It’s all too frequently the case with these alleged conspiracies that the people who subscribe to them have not examined evidence from both sides. There seems to be a tendency to form a conclusion before a thorough critical examination of the evidence. Also, many people are seemingly incapable of determining what good evidence actually means.
For example I’ve spoken to people who believe all sorts of craziness because a website/YouTube video has posted an explanation with no empirical evidence or credible sources.
Please look at both sides of the argument, examine who has the most evidence/most reliable evidence and then form a conclusion. The last time I looked in to this, all of the conspiracy theories surrounding the controlled demolition of the towers was completely evicerated by numerous highly respected experts in their respective fields. A glance through that website is offering no new compelling evidence that makes me want to change my mind.
Conspiracies definitely exist, but they’re ususally of the more mundane CIA assaniation, subtefuge variety and even they usually get exposed. Apart from the lack of credible evidence, I just don’t think the US Government has the competency to pull it off.
