What is it with you and links to movies. I never bother looking because it's never funny
Back to the original topic - you seem to think it's appropriate/fair to respond with ridicule to someone stating a belief rather than addressing the actual topic. Why is that?
Think about the topic for a second. If a government official states a belief that these things (whatever they are) are real then the next logical question would be what are you going to do about it and that's the problem. We have no f'ng answer and that's why they avoid the question.
For a long time the US governments response was that they posed no threat to National Security. They didn't deny the existence - they just ignored the original question.
