If Assange  considers the 9/11 research outcome not important, what better gatekeeper can you have? See how an extremely nervous Assange tries to avoid the issue (like Chomsky w/similar questions).
Assange - "On the 9/11 issue generally, I don't think it is particularly important."
This video shows shows us Julian Assange in 2017 at the Holberg Debate, answering a question whether or not a new investigation into 9/11 would be justified
Assange's response doesn't really differ from his earlier statement in the Belfast Telegraph from 2010. This time however, he is much more on his qui vive and he clearly struggles in the direction of damage control.
In fact, it is mind-boggling as he formulates (exactly like Noam Chomsky with similar questions about 9/11 or the JFK-assassination) that the outcome of questions about 9/11 does not really matter, because there are more important issues nowadays.
Quote Julian Assange, Holberg Debate; Saturday, December 2, 2017
"On the 9/11 issue generally, I don't think it is particularly important. In a sense that every day or every few weeks, Wikileaks and some other publishers publish proof of very serious existing conspiracies that are happening right now or just a couple of years ago. In order to start wars or steal billions of dollars. These things I think can have more over a change.
There's a certain view in relation to 9/11 that it's somekind of holy grail that would shake the existing order of things, but I don't think it would, even if it came out that there were some rogues, ehh.. rogue agents involved."

What about 9/11? "I'm constantly annoyed that people are distracted by false conspiracies such as 9/11, when all around we provide evidence of real conspiracies, for war or mass financial fraud."
