Have you heard about the dancing Israelis on 9/11? There are many news articles and also declassified FBI documents on the subject.
Unfortunately this is quite a deep rabbit hole of dis- and mis- information... I would not quote the dancing Israelis as a primary source - so many more obvious ones that are self-evident. All you have to really do is quote the criminals; they constantly brag about what they do. In terms of who is in charge at the top... Well that is a much deeper matter.
