if asked i would tell the investigating officer that i had to shoot to live ...
Shoot the lit bottle in his hand and let him feel the pain of his own soon to be action. then go out and fan the flames.
... The instructor went through all the legal costs associated with a questionable shoot,the probable economic losses of job opportunities,freinds that shy away from you, and other related issues. The conservative calculation was 50 grand to protect a 15 thousand dollar car.
He also pointed out that once you go outside to catch a thief,you expose yourself to not knowing how many partners the thief has with him,if they are armed,and where they may be hiding--a situation in which you will never find a police officer without back-up.
It is easy to play that little movie in your head about how you are a hero for shooting a bad guy, but you focus has to be on evaluating the threat,warning the threat that he has to drop his weapon,and stopping the threat if he continues to threaten your in a manner that causes immediate lethal danger. Again,this is not legal advice,just my understanding of what my instructor stated.
