Good evidence that Mossad had foreknowledge and were possibly handling the attackers but I think the most important thing now is to focus all these years later on the response to the crisis. In the end it really wouldn't have mattered who did it for the likes of Wolfowitz, Feith, Bush et al they were going to use it to go to war largely for the benefit of Israel. That's probably the most important part at this late stage.

If you're interested in the technical details of the buildings collapsing and the utter absurdity of the mainstream explanation then I recommend the videos by a group called Architects and Engineers for 9/11 Truth. Very detail focused and not at all political. That's the type of thing which I think is good for winning the 'normies' as well.
