Loaded with double-aught buckshot, the instrument of home defense depicted below has the power to separate the soul from the body in a manner most definitive. Just showing this bad boy to a would-be home invader is a most effective way to issue a 'trigger warning' in a reality-based sense of that phrase.
But let Uncle Bill give you a piece of friendly advice. You really don't want to have to shoot anyone. No matter how worthless the scumbag, he is some mother's son and a bearer, somewhere deep inside under a load of corruption, of the imago Dei. Taking a human life must always be the last resort, and this for moral, legal, prudential, and psychological reasons. You should aspire to die a virgin in this regard, assuming you are still 'intact.'
So here's my advice. Secure your home so that the miscreants cannot get in. That's Job One.
And of course never, ever, vote for criminal-coddling, criminal-releasing and gun-grabbing Democrats or liberals and always speak out loudly, proudly, and publicly for your Second Amendment rights. It is the Second that is the real-world back-up of the First and the others.
