Shel- if you're living with the thought of having an attack always in the back of your mind, that is exactly what they [gov't] wants. Whether they did the attack or not b/c it is the foundation of such unjust laws as the Patriot Act.
That said and coming to the conclusion with overwhelming evidence that 9/11 was directly connected to the gov't and specifically the Bush Administration [imo] it is evident it was just the introduction to a new world order. or should we say "war on terrorism", your choice.
