Enlighten me then. What do security guards armed with pistols or batons or tasers train on then? If I hired them to protect my store then why would I want someone who is incapable of killing a threat? I mean of course the description will say “disable” or “neutralize” the threat.
I have no idea, but the wannabe cops you’re talking about are absolutely nothing like the average security guard. The average security guard is a pudgy, retired old person with bad knees who wanted a job where they basically don’t have to work and would literally flee the scene if anything violent took place anywhere near them.
Yes and I’m assuming most people do not care about some old guy chasing you down for a candy bar.
The OP said security exists on a spectrum. The job is part power projection and part power execution. No different than a sailor whose job is to sail a destroyer around the world without firing an missile and a marine deployed in Afghanistan. We all serve and protect capital at the end of the day. Some of us more than others.
