I had to add my 2 cents. Here in Maryland there was a shop that was burgularized on a regular basis, so the owners decided to hide out in the shop and guess what? The idiot robbers came back again, needless to say not all of the robbers came out alive. The states attorney is now still deciding whether or not to charge the owners of the shop with murder.

Like the two sign says each one of basement doors on my basement door:
"THERE IS NOTHING IN THIS HOUSE WORTH YOUR LIFE"
"IF YOU ENTER THROUGH THIS DOOR, YOU WILL BE KILLED"
