There is not much point trying to convince someone he doesn’t need what he has, because he might. You can’t prove a negative.

But once you have a basic shotgun, you might want to ascertain that you’ve got functioning smoke and CO detectors, fire extinguishers, a good first aid kit, and maybe a disposable smoke hood ready, before you spend a lot of time fancying up your shotgun because you’re worried it might be insufficient.

Because there are ways to die in your house that are a lot more common and statistically likely than an attack by a group of homicidal intruders so large and fanatical they won’t be deterred by 5 loads of buckshot.
