Even if you convinced the whole country that 9/11 was an inside job, and arrested and convicted every single person involved, it would accomplish almost nothing. More bad people would replace the displaced ones almost immediately. Clever legislation might even make things worse.
The problem with our country is not that there are some bad people in power, it's that the people put and keep bad people in power, and they do that because they are not "converted" to the principles of good government. If a critical mass of people with good political principles is active in the process, then the bad people will be removed organically.
Perhaps it's naive to think that it's even possible to get anywhere with that approach, but nothing else can do any better as I see it.
