Ya know, I got asked a question the other day (during a kind of interview about flying century series era fighters) if I had been in any scary situations or scrapes or really bad situations. I've certainly had my share of systems failures and tangles with weather (including having both engines compressor stall; when you've only got two that gets your attention) but none of them REALLY stood out as an aw sH!t gonna die moment (Mother Nature has probably given me the scariest rides of my life anyway). Most of that was because we simply kept the airplane flying and worked the procedures around this; we were doing what we trained for (realizing that there are many things not in the 'book') and it resulted in a positive outcome--no big deal. I think having a big picture (as an LE) and deescalating things is the same concept; you stop things in a situation such that they don't snowball into something REALLY bad. Rather than escalating them. Effectively using knowledge, experience, training, and common sense to nip things in the bud before they GOT into a really bad situation. I see the mask BS as a part of this. So a woman doesn't want to wear a mask (on public--not private--property). So what ? You don't have her assaulting anyone (in fact a year ago this'd be perfectly normal; it's the wacko paradigm that's shifted and people have gotten caught up in it). You might ask her to stay away from folks that might be for some reason afraid of her but let it go at that. Telling her "look, there are some folks here who are petrified--for whatever reason--of what they've heard on the news right or wrong. Can you keep your distance and not get in their face if they're from among that group and keep a low profile while doing your thing ? We're not FORCING you to mask up just to kinda respect others' space and not get in their face).
