But so a cover up was done as telling the truth might be embarrassing and uncontrollable... But were the people in charge that to leave such a vacuum has meant that there is no reposte to any and every theory?

So, we know that the truth must have been viewed as worse than the government being complicit in a cover up. What could be that bad?

In the case of the modern event I feel that the actions prior to the day were the problem, namely the monstrous arrogance of the USA that the entire world appreciates their ham fisted and usually myopic attempts to sort out problems that are not as simple as their leaders hope.
