As Brian pointed out, there are many things about this attack that are still unknown. I can't fault anyone for waiting to have the necessary facts before making a decision. As a democratic nation, we hold certain beliefs to be true. Innocent until proven guilty comes to mind.
With 4000 FBI agents and 3000 support personnel dedicated to the task, I feel certain that we will soon have all the evidence we need to reveal to the world who the guilty are. When we do, I think Senator John McCain R-Ariz. expressed it most appropriately..."I say to our enemies, we are coming. God may show you mercy. We will not."
