I think whether the government was involved in 9/11 is irrelevant. Seriously who cares? I don't think the American public even cares. How do I know this? A simple example is the Iraq war. One doesn't need to be a genius to understand the immorality and illegality of that war before it started. After it became fact that the "reasons" for starting the war were complete bullshit, what did the American public do? Nothing, we did absolutely nothing. Patriot act, escalation of the Afghanistan war, drone strikes killing innocent civilians, targeted assassinations of American citizens, indefinite detention, etc. All these actions, and more, by government are just as bad or even worse than 9/11.
