if I was the father I would have done the same. if the daughter said she didn't know the guy you don't ask questions. you protect you daughter by all means. you have to think in less than second of what to do to protect your family. any more time than that it gives the intruder time to react and could mean a family member or your life. hate it for them because now the dad will have to live with the fact he took a life and the daughter because she lied caused this boy to die. it will be hard on both of them. but if I was the father I would pulled the trigger.
