Here's the scenero. It's 11:30 pm. You are sleeping in your bed and hear somebody break into your house by forcing the front door. You have a pistol in your nightstand and you take it out of the drawer and make sure it is loaded. You get out of your bed, turn on your bedroom light and step out into the hallway. As you do, you notice a person climbing your stairway and the person has a knife in their hand. Would you shoot this person or not shoot this person? I would shoot this person.
