The irony though, is that statistically speaking, gun owners are more likely to be killed in home intrusions than non-gun owners.
What people don't seem to consider is that most intruders are not in your house to kill you - they are there to steal your
valuables. However, if they start thinking they aren't going to be able to do that and get away with it, many of them will ramp
up the amount of force they're willing to do to avoid consequences (especially in places like the U.S in states with
three-strikes rules).
If somebody comes into your house, and you just sleep on, they're likely to leave once they have what they came for -
However, if you alert them you might very well have an encounter on your hand, and that encounter might just as well
end in your death as in the death of the intruder.
While I generally don't like 4chan logic, the statement "trying is the first step to failing" rings true in this scenario,
because failure is a true option even with a gun, and it's much easier to avoid by simply not trying in the first place.
What's more important to you? Your things, which you can have insured? Or your life?
Fact of the matter - you don't know who's in your house if you hear something. It could be one unarmed hungry hobo, or
it could be 2-3 guys in a burglary ring armed with anything from 9mms to crowbars.
You take out your pistol, and start going down the stairs.
Maybe you shoot one of them, and then another of them shoots or hits you in the back. Now they're in a frenzy and looking
to get rid of witnesses before leaving your place so they kill your family too as insurance.
Now, is this a likely scenario? Not very. However, every burglary is a Schrödinger's death-trap waiting to happen,
and it's more likely to happen if you take out your gun thinking to play the hero of the day.
Just saying - and I'm "just saying it" as a person who's worked in the private security sector, as among other things,
a body-guard (I'm willing to put up credentials if you find that hard to believe given the forum we're on).
