When I was 16 a couple of guys from the nighbouring town broke into their teachers house, thinking he was away on vacation, to steal his liquor (stupid obviously) anyway the teacher was home, took out his legal hand gun and fired blindly into the dark (not seeing these 14 year old boys) and killed one. Ya, self defence is great. Unfortunatly what this guy didn't know is that Canada doesn't have self defence laws and he is now serving time for manslaughter.
