A friend of mine was a grocery store owner, who lived across the street from his store. His wife heard glass break, so he retrieved his Glock 21 (.45 cal) and ran to confront the burglar. He saw the guy through the window, and he looked like he had something in his hand. My friend ducked behind a wall and ordered him to put his hands up. Instead, the guy made threatening motions. My friend fired from outside the store through the window and killed the guy outright. The problem was the guy didn't have a gun, was inside the store, and all he had in his hand was a pocket knife. The police came, questioned him profusely and then confiscated his weapon. He wasn't arrested, but he spent several months wandering whether he would be charged with murder. He was finally exonerated by the Commonwealth's Attorney. That may be because we live in a predominantly rural environment where it takes time for the police to respond, and my friend was engaged in a quick-second decision whether to fire or not to fire against a criminal with a long record.. In other towns in Virginia, my friend might be doing time for defending his store. It just depends on the prosecutor.
