Oh I agree.
But that doesn’t take in to account for human behavior
Reminds me of the time my brother-in-law's wife worked for a brief time as a security guard for a store. She was obese and about 4foot & 10inches, and never had any fight training. My thought was, "you've got to be kidding, someone hired you?". Wrong people for the jobs. Two of my other brothers-in-law became SF cops, but they had fight experience and could handle it, one is a karate black belt. You can't do the job, don't take the job doing security.
