it seems to me that the government had a duty to perform that day, and the day's leading to it. the complete and total failure, four separate times in one day by norad is unacceptable. there was absolutely no evidence that planes brought the towers down, the evidence was removed and destroyed. why isn't there a criminal investigation into everybody involved in the destruction of evidence? that just screams cover up. the evidence of the deaths of over 3000 american's, of an unprecedented building collapse, three of them, no less. the safety issues of future building codes that needed that evidence to prevent it from happening again, and to find the truth of why? it's insane that the total cost, or rather investment, in an investigation of events was only $400,000 and the investigation into bill clinton's legal, no deaths involved, affair was something like $6 million. along with the reams of missing testimony, the claims by the investigators the whole thing was a sham, some resigning, is all the proof necessary.
