Two people are having a fight. They are throwing punches, kicking, elbowing, ETC. One eventually begins to gain the upper hand. The person on the losing end happens to be carrying a weapon. At what point are they justified in using it?
Would they be justified if the person winning the fight was a relative of yours?-Paul
