Apparently, this intruder was high as a kite.
Attempted Intruder Shot Dead By 17-Year-Old
I feel bad for the 17 year old and for the deceased. However, what else are you supposed to assume when someone is trying to break into your home and acting like a nut job? Unfortunately, in this day and age, you have to assume the worst or you (or your homies) might be the one lying in chalk. Certainly, with the way the intruder was acting, I would fear for my safety as well as everyone else in the house.
