Stop crying
Let's see if I can penetrate your self-serving fog.
You are charged with murder. You file as a defense that you could not have committed the murder because it happened in your hometown at a time when you were actually attending a convention on the planet Uranus with others of your ilk. While you might be assumed to want to be at such convention, that sort of alibi defense is going to require EVIDENCE from YOU to show that you had the means to travel to Uranus from earth and back. Evidence of a claim that your residence is Uranus, though plausible depending on spelling, will not suffice to explain how you got there and back. Your defense would be an "affirmative defense" raised by you ad requiring proof from you, unlike most defenses in criminal matters.
If that does not suffice to penetrate your fog, don't bother responding. I know what I am talking about and YOU clearly don't. No surprise on either count.
