The issue of course is that violent crime in general is reported in such a way to make the layman (such as your father) feel that it is hyper-likely to happen, when in fact it is much less likely to occur today than it was back when he was your age. Whatever your age is.
A semi-related anecdote that may or may not be bearing… I just enjoy telling the story.
Years ago I took martial arts (to keep weight off and as a sport), and every once in a while the instructor would teach us some Hapkido techniques to deflect punches, disarm a knife-wielding attacker, break an attacker’s arm, etc. One day while we were practicing a knife-disarming move, one of the students asked the sensei about the best technique to use against someone with a gun.
The instructor thought for a moment, then nodded. “If,” he said, “you are robbed at gunpoint and the criminal is within arms’ reach, do the following: Get into your ready stance.”
We all complied, standing with our weight primarily on our back feet, elbows relaxed.
He continued: “with your primary hand open, slowly shift the arm behind you.”
We did as he was showing us.
“Then, in a slow, fluid movement, remove you wallet and hand it to the robber.”
We all just stared at him for a few seconds before chucking. He then proceed to lecture us about the appropriate times to use deadly force - in his view (like mine today), force was only to be used to protect yourself and others. As reasonably well-off middle-classers, there was effectively no situation in which deadly or even maiming-level force should be used to protect material “stuff”. Instead of concentrating on what move you might make to potentially take down a robber, he advised, use that time to memorize his face, his stance, his clothing, his accent, and especially any distinguishing marks that you could use to positively identify the criminal later on.
Yeah, but what no one is saying (including yours truly) is that a valid threat to one’s health or the health of your dependents should not be met with all due reasonable force, up to an including an armed response. In my previous scenario, if the intruder were to venture upstairs to where my family and I were cowering - despite my warnings that I was armed and would shoot him - I would absolutely attempt to kill him.
