Creative Speculation

If I understand what you're driving at, you're arguing that there was no inside job. So you think the job could have been pulled of with zero people inside our government involved in it.

If you're right then isn't it also feasible for the job to have been pulled off with all the same people whom you believe did it, plus one single operative inside one of our covert services? Or, alternatively, all the same people whom you believe did it, plus some small tight-knit cadre of people from inside our government. For example, Dick Cheney together with two or three CIA operatives?

That latter example would still be an inside job. Why is that theory not viable? It seems to me you're building up this cast of thousands just so you can knock it down. In other words, you seem to be battling a straw man, no?
