It seems like everyone likes to think in worst case scenarios, two 6'5", +300lb'ers raping your wife and kids, what would you do situations. In the grand scheme of things, that is highly, I mean highly unlikely. With that said, I like to plan for worst case scenario too. In which case all bets are off when the safety of my loved one are concerned and someone is dying for putting their hands on them. I'm sure the majority of you out their feel the same. Here is the thing though, that is maybe the 1% of home invasions. Tell me, when was the last time there was a headline like that? I know, I know what if? If your planning on worst case scenario, ask yourself, did you prepare for the other 99% of the time? I don't have any statistics but probably a good majority of would be criminals would pass your house if your lights would turn (i.e. motion sensor lights) A good motion sensor light cost less than $20 bucks. I think $20 is worth your family's safety? How about a good deadbolt? There are lots of things that would deter a good majority of worst case scenarios. So why not make the percentages work in your favor? Personally I'd rather not shoot anyone if I could help it.
