Non-Extrapolation

Going to try to put this into words. It's pretty much a complete thought, but...
You can look at almost anyone and see what kind of violence they can expect. There are outliers, sure, and often training time has to go into the high-stakes/Low-frequency stuff. I'm actually looking at it from the other direction.
Lawrence works stadium security. He's a supervisor. That means he has a lot of experience with putting down college-age kids. Usually bigger and stronger than he is, but drunk and stupid and inexperienced. Also, he is usually drawn to the action, which means he has a little time to mentally prepare and he is coming in with the coolest head.
That doesn't denigrate his experience. It is a valid place to have concerns about safety. It requires real, not imaginary skills. I'd rather have his advice in a soccer riot than anyone else I know.
There's a bouncer look that some people go for: shaved head and sometimes tats and a little bulky... that very look almost guarantees that ninety percent or more of the violence they will be exposed to will be, again, a drunken college age man. Someone who will challenge directly, "You don't look so tough!" And will give plenty of warning.
M doesn't have that look, though he was in that life for a while. He's old enough that he won't get challenged often by the young bucks. If he is attacked it will be by an old enemy and it will be silent and brutal and from behind. Side effect of the world he lived in.
S is a tiny woman, very pretty. She risks an unguarded moment and then a hand on her arm an someone showing her the knife or the gun, "Come with me. Don't scream. Don't make me hurt you."
Another woman lives with high risk behavior and spends time around high-risk people. She will become used to, even expect, certain types of violence. hen it happens it will be direct and close range from someone stronger, faster and more vicious and it will happen while she is trying to manage the potential conflict in a social mode. Maybe apologizing or placating or even tentatively attempting to set boundaries.
There are outliers: Home invasions which can suck no matter the victim profile and may or may not have been researched by the criminal (most will be). A mugging may be anything from displaying a weapon for money to a brutal, quick pack attack...or even a not particularly brutal pack attack. The victim profile for those ranges, but hits close to a basic risk/reward equation. A bonding-style group monkey dance can hit almost anyone...
When we, as instructors, pretend that our experience extends everywhere, we're probably snowing ourselves even more than the students. An officer who has responded to calls a hundred times with armor and weapons and back-up on the way may not be able to really understand, much less prescribe answers for, the college girl locked in her dorm room with a guy who may not be as compatible as she first hoped.
Even those of us with experience got a specific type of experience. There is not a lot of experience with the most dangerous stuff because it is damnably difficult to survive enough to figure out what works.
