The more complex and coordinated the more it appears that Al Queda is a growing rather than diminishing threat
If it was a lone whacko who worships Osama as his hero then that wouldn't make Al Quedia look like a big bad wolf. And it wouldn't drive the ratings up... The media wants a "complicated" conspiracy that they can ferret out.
the truth is the simpler the plan, the less likely it is to be pre-discovered...
