In an ideal world...

...I will be armed if I see a UFO. 

Think about it. If you have questions if they exist, what faster way could there be to prove/disprove the idea than to shoot at one when in range. Best case scenario: I shoot it down. I become an international hero/superstar. I'm worshipped by nerds the world over. I make billions off of the wreckage. Worst case scenario: I shoot it down. I die a slow, painful death from radiation poisoning I got from investigating the wreckage. I start an intergalactic war that is quickly and ridiculously lost to our new over-lords because our lack of being intergalactic.  I get "abducted" in the butt.

In an ideal world, I won't be armed.
