I don't understand. Where does the bravery come in?
All I see, is that the two-bit criminals got shit scared by someone coming out with a shotgun, threatening to give them wonderful face make-over.
Burglars don't kill people, ever, only if their life is in danger, because if they kill you, it'll attract plenty of police attention, so scaring them off or shooting them is meaningless, to be honest with you.
But yeah, atleast the window only needed replacing, just need to keep the stuff hidden up / safely locked up.
