Why else would there be such a massive government coverup of the alleged event? 
I work for the state government. When I hear people refer to a "massive government cover-up" or a multi-agency conspiracy, I laugh. Bureaucracy is inefficient, uncoordinated, and each agency hoards information since information is power.
I'm not saying government conspiracies don't exist; Just that they are uncommon. Usually things get swept under the rug out of sheer laziness, not nefarious reasons.
Considering what I have seen in my 15 years in state government, I sincerely doubt that the government conspiracies even exist. There is too much laziness, guesswork, poor decisions, and general loose lips for me to be anything but the cynical cuss I am today.
Last month, we went on line with a nation wide database that tracks car titles issued in the US. That way, when someone presents us with a title from another state, we can check and know for certain that the title in front of us is the true title.
Except, the guy last week had a title issued in 2011, but the database said that the most recent title was issued in 2005. I ended up making several phone calls to this other state, and confirmed that the 2011 record had not been updated, but it was the most recent title.
Only now, other state is sending ME (lil' ol' peon Me) car title information, and telling me to access the national database and make these changes. Um, no. Just no. I am not the contact person for my state, and I do not have the authority to do anything remotely like this. I only got them to stop by having the head honchos in my state call other state directly and say, "Leave lil' Pierrot alone! She's a nobody!"
