Thank you for providing more than a story three parties removed from you. I spend a lot of time in court with my job so I’ve accepted that any goofy theory can be brought forward but most get thrown out as the case moves up the system. Rulings in the lower courts can be scary. After years of researching this subject the best summery I’ve heard is this, if you are ever in a self-defense situation you will be arrested, go through court system, and spend a boat load of money defending yourself. Take anything else a bonus.
