Stand your ground laws really need to be changed so that you actually need to be standing your ground. The idea of pursuing an unarmed man and then shooting him in self defense is ludicrous, regardless of any other facts.
Absolutely. If by your actions you instigate the event that is on you, not the other way around (which IDK how the law is necessarily written but that would seem to be the intent, that the action has to be done upon you). Obviously that's not how this went down, but Ahmaud in this exact situation would have had the right to stand his ground, he was just minding his own business and then was being pursued. The guy pursuing has zero right to self defense/stand your ground laws even if Ahmaud strikes back because he was the one causing the situation to happen.
Maybe those racist assholes assumed the best self defense was a self offense.
