A word of advice. If you take pot-shots at someone in the dark across a long distance (50yrds), even if they opened fire first, a good prosecutor will eat you alive.
i don't know where you live or what you call a "good prosecutor". In the state of OK the prosecutor would be required to give the shooter a pass if he/she was fired on first. The idea that a person on his own property, minding his own business could not legally return fire is absurd.
Oklahoma is pretty good on self defense shootings. In OK the prosecutor can decline to take a good shoot to the grand jury. Our last prosecutor gave three passes on lethal self defense shoots in a 18 month period. One of them was the shooting at the link below.
