Let's say I show up on this message board and say my house is more secure than a bank vault, because I have a special laser in my attic that vaporizes attackers if they come in my house. Would you believe me? Would you bother to even visit my house to prove me wrong? I mean, I can claim all I want that nobody has robbed my house, but at some point there is actually nothing of value here that means nobody has tried and nobody actually wants to try.
