This AZ gun lawyer lays it out pretty clearly what to do when to considering use of deadly force. Remember: A jury weighs cases on facts within interpretation of the law. The question will be...was your conduct reasonable under the law? The problem is...do you want to trust what a jury might determine is reasonable? No, so if in a sticky self-defense situation, be sure to quickly evaluate this instead: Is being prosecuted better than whatever outcome might happen if I decide I need to draw/fire my firearm? Yes or no? Draw/fire accordingly...
