Chomsky is DEAD wrong about 9/11

Here's a good essay on the "Dissident Voice" website dealing with the reluctance of academia to investigate what really happened on 9/11:

And here is an excellent website which lays out the basic problem:

Frankly, so-called academics are ALL beholden to government or institutional funding which would vanish if they seriously tackled the reality of 9/11.

This issue makes me question the relevance of Professor Chomsky. Does anything he does or says make a difference, or is he merely a kind of safety valve who keeps certain issues from boiling over into effective action?
