Does that sound like a movie script? Hell, I read about those real-life scenes every day in the paper.
Yeah, it kinda does if you're a secret agent or a professional assassin.
I can honestly say I have never seen anything in the paper that required that level of caution to avoid trouble.
Further, the idea some criminal mastermind is going to silently break into ones home, stumble upon your weapon (not having one of his own), and finally use it against you as you stumble into his nefarious activities is laughable.
Is it possible: sure. But if it actually happened I'd have to conclude God is after me.
But serious drug-driven crime has occurred to people close to me, including family members. In one instance an elderly woman and her three grandchildren were murdered, in her home in broad daylight, shot in the head with a .25-06 rifle by a deranged addict who had somehow concluded they were the enemy.
And friends of mine--people with nice, isolated homes and valuable possessions--have in fact fallen victim to home invaders who spent considerable time (days, in one instance) locating, selecting and removing (or destroying) said possessions.
If you are just that smugly reassured by your local newspaper and your own highly tuned security acumen, I am happy for you.
You might want to save your counsel and your insolence for those who haven't experienced otherwise.
