I'm under the impression that although this took much planning and precision,that not many people we're directly involved with each of the hijackings. This to me, means there's a shitload of cells inactive living amongst us.
I'm not stating we need to round people up, I'm just curious as to what people think about further actions from ground based cells, such as bombings.
I was on the edge of my seat when the hundreds of people were walking across the bridges half expecting explosives to finish the devastation in NYC. Perhaps they will hold off until we've begun our counter-attack...
