I agree with you Ron, all this focus on far-fetched conspiracies is conveniently distracting from finding out who, in the upper echelons, fucked up. As is usually the case when something goes wrong to this magnitude there are people who were asleep at the switch and the cover ups begin. It is in the interest of those who fucked up to keep the wild theories fermenting as this puts the hounds off their scent.

I believe we are not being told everything that the government knows but the purpose is to protect their own who came up short when they should have taken action on the information they had. As is most often the case in human tragedies the cause is one of human failure.
