If Alex Jones were really a threat to anything significant, he'd have been suicided long ago.
One would think that, but since Alex is not the only voice out there, and most of the info I have found out about 9/11 did not come from Alex, actually almost all of it didn't, killing him would not stop the 9/11 truth movement one iota. Actually it would do the opposite. Also, whether Alex is sincere in his efforts to uncover the truth or not doesn't really matter, the truth for the most part is already out there. The 9/11 truth movement is huge and will not go away as long as people can still think. The government can't put this genie back in the bottle no matter how hard they try. To be honest, I think this is exactly the way TPTB want it. They screwed up 9/11 too bad to not want the truth to be known by the populace. What the plan is I don't know, but I have a feeling that it is not good.
