There are many inconsistencies between the official OCB story and the evidence:
The hardest question to answer for the skeptic is why?
Perhaps testing the public and official response to an outrageous event is a good idea if you have a bigger ‘event’ planned down the road.
You can learn lessons on how manage:
Evidence that the event was known about before it happens
Building structures not responding to the physics correctly and the expert witnesses who are prepared to testify to the fact
The media response and managing public perceptions to give people an easy excuse to dismiss the event as the act of ‘extremists’.
Conditioning the public to adopt a cult like unquestioning attitude to ‘terrorist’ events leading to the ultimate objective – if you question the official story perhaps YOU are a terrorist.
and so on …
in other words society wide trauma based mind control
