"This fine line is called excessive force. During the course of defending yourself you cannot use force greater than what it takes to stop the attack. Where this line is drawn depends greatly on what state you are in, the type of attack, the victim and the attacker. There are so many variables that it often becomes hard to define what is self defense and what is a counter attack."

"The use of weapons is another very touchy matter. Again, you cannot use more force than what it takes to stop the attack, and the use of any deadly weapon is a crime unless you feel that your life is in imminent danger, and can prove that you thought beyond doubt that your life was in danger."
