Hahaha ...factual evidence.
If there's a 1% chance that bombs were used, every American should want a second investigation, as the original 911 commissioners do.
Based upon firefighter statements, videotaped evidence of giant "booms", seismic proof, and many other things, I think that 1% is far more than reached.
If there's a 1% chance that somebody not named those 19 pricks was involved, then every patriotic american should support an investigation.
