Afghan inventor Hanif Molavizadeh, an unemployed electrical engineer, makes his own home burglar alarm using a Kalashnikov rifle. Once an intruder triggers the alarm's motion detectors , it will set off a song-like warning. An automated voice then warns him on his cellphone that there is an intruder. He can then remote-fire the Kalashnikov attached to the wooden box of his alarm. If that doesn't scare away burglars, I think nothing will.
