Yes. I have a back door too. Those that burgled our house however, didn't bother knocking either. They just smashed the glass and came in uninvited. They actually crossed onto my land (across my boundary) via a 4' wall. Your point?
burgled yer house noseall ?
Doubt they caught the burglars either ?
did they pinch yer carpets ? If so that
might give you a clue as to who they were
