The reports said they were fairly sophisticated weapons. I also believe he could have had an accomplice who fled during the evacuation after the attack was foiled. Also, shouldn't they have traced the serial number of the guns by now? Why haven't we heard anything as to the origin of those weapons?
I think/believe the true Al Q method will be to try to replicate 9-11
They would probably like to replicate 9/11 but I doubt they could pull off something like that again with security being what it is now - unless they go biological. I think when the time is right they will use suicide bombers. We successfully broke up their training camps in Afghanistan but where are the thousands who already passed through over the last 8 years?
Just my own thoughts, but I would suspect them of trying for a knockout punch on this coming 9/11.
If they try doing suicide bombings on schools, etc, the government had better inter all the Muslims that they can find still alive. And, they had better put lots and lots of guards around those camps. I don't think the American people would be as forgiving as the Israelis. I really can't see them doing suicide bombings in the States, but that is just my two cents.
