Eleven Mike, we are allowed to own all sorts of nifty firearms, we are just not allowed to keep them loaded and/or unlocked in the home. As a matter of fact I was told that, under Canadian law, if you feel threatened during a break in, you are obligated to attempt to flee your own house! If you defend your home and the BG gets hurt, you must be able to demonstrate that you were unable to flee!
PS: A bingo hammer is one of those little tack hammers that the little old ladies use to fasten down their bingo cards. It might not be an effective defensive weapon but it may keep the BG off his guard long enough to get out your bow and arrow ...
