Many people believe this. You've been sold on this idea.
It's in the governments interests to present themselves as incompetent so when shit hits the fan they'll be the last people you suspect in doing such a thing.
Governments are capable of doing things efficiently and chaos.
Keep dreaming. So incompetence is intentional?
Let me ask you another question -
Many of you try to convince us that the buildings were brought down by controlled demolitions.
Are we to believe that all of the security guards were in on this two and they did not see any of the teams laying the bombs in the days leading up to 9/11?
The alarm company did not notice anything either?
