If a man breaks into your house, he will kill you. That has to be the mental mindset of the legal person in the house because one cannot know whether the person would kill you or not, so you must assume he will kill you. You don't have my book yet, inside are instructions what to do now so you know someone is breaking in and you can stop them before they get in. It doesn't cost much to have those detectors but you have to know which ones work. They will work even for you living in a hut in the great outdoors. 
@Victoria33 Sure - I am gonna come at that with the prejudice of a double-tap, there ain't a doubt in my mind. I ain't going to check to see if he's armed, I ain't going to make him aware of my presence... Just two from the shadows, and then we'll see past that...
And if there are three of them... well, all the more so. With three to worry about (and maybe more), I won't be leaving injured on my six that might come back to haunt me.
As to my protection IRL, my first defense is always a dog - Nothing gets on the property that I don't hear about. Though I will admit that ol Chewy is getting on in years, and ain't as alert as he once was. Still, he will be their first concern, which will give me enough time to be ready.
And let's not forget my redneck tech degree... With a word I can employ full surveillance (to include IR night sight), flood lights, and a claxton... Not to mention electronic countermeasures that will not be enumerated here.
Not that I expect any of that to be even vaguely necessary. Any random villain casing the joint is going to see all the redneck man-junk in the yard, and the dog, and do the math. He is going to know upfront I am armed and that I will very probably know he's coming... Criminals are opportunist, and that all adds up to going to find greener pastures.
Which leaves only um... business associates... or folks with a personal axe to grind... And they all know better.
So not to worry none about me. I'll be fine.
