In the dojo in LA once we practiced gun disarms* and sensei mentioned that there was a LAPD cop who came in for private CQC training and they focused a lot on that

which at the time (mid-late 2000s, with Rodney King and Rampart still in the air) felt a little sketchy, like here’s this cop who practices fighting people for fun

but now feels a little honorable, like here’s this cop who channels whatever “let’s beat someone up” frustrations and energies into developing the confidence to resolve tough situations without shooting someone

* I can’t reliably do this at all, and I know trying and failing might radically raise my chances of losing the encounter, but so might putting up with a holdup and letting myself be maneuvered to a second location, at least I have the option (plus I perform better under stress, in my most serious street combat I got the bullet-time slowdown effect and used it to audible a strike around a block). On the other hand, if you come running at my field of vision with a 1m melee weapon held at the end like a club or sword that you aren’t specifically trained in, I’m pretty good
