@ReluctantDecoy my initial training, that goes back some 40 years now included that you don't shoot to protect property, and you can't use deadly force once the threat has removed itself by running away.
It would be nice to be able to chase the bad guy down and shoot him in the back for stealing a pack of smokes or a six pack, after they displayed a weapon in the process, but unfortunately that is not the way the law works in a supposed civilized society.
There is also the strong possibility that no matter how justified the shooting is, you are going to be arrested, cuffed, stuffed, held for arraignment, have to sit there until you come up with several hundreds of thousands of dollars for bail, find a competent attorney who can save you from PMITA prison, try to raise money for their retainer since you broke the bank raising bail money, etc etc etc.
Trying to teach people how to shoot and safely carry a concealed weapon is easy, beating it into their heads when they are legally allowed to use deadly force is a lot harder. I always suggest Massad Ayoob's book " In The Gravest Extreme" as required reading
