HELENA, Mont. (AP) — A Montana man is accused of setting a trap and blindly blasting a shotgun into his garage, killing a 17-year-old German exchange student. A Minnesota man is convicted of lying in wait in his basement for two teenagers and killing them during a break-in.

The two recent cases take the “stand your ground” debate to a new level: Do laws that allow private citizens to protect their property also let them set a trap and wait for someone to kill?
