I agree wholeheartedly with model520fan that the answer to the OP is shoot where it's necessary to avoid death or serious injury, and do not shoot where it is not. That'll keep you out of trouble, for the most part.
It is also my opinion that a gun forum, particularly one titled concealed carry methods and issues, is a very appropriate place for questions and discussion about the laws of self defense.
