911 Review.org lists many articles pointing out that it was an inside job.
Personally, I find the whole thing offensive because I believe the Bush Presidency was so ready to act on this that they were quickly able to switch from blocking research into who/what caused these attacks to pushing the US Military to attack non-threatening countries, and neither parties did anything to stop the unjustified war afterwards.
Republicans and Democrats alike are allowing this atrocity to stand.
Bush must be impeached as a traitor to the USA, along with Cheney, Rumsfield, and Rice. These people have blood on their hands -- both American and foreign.
