Truer words, as they say. NO MATTER WHAT your gun sounds like when you cock/chamber/load it, if you're not ready to USE it, and to use it CENTER MASS, while keeping YOURSELF SAFE, then you should simply lock the bedroom doors and use a cellphone to call police.
I actually know folks who keep their pumpguns UNLOADED, and intend to "just rack the slide, that'll scare 'em off!". Needless to say, I strongly advise them against this, but there are seemingly THOUSANDS of jobrones who are quite ready to repeat this foolish tactic to them.
