Doghouse95, I understand your anxiety. It's one thing to have a diminutive daughter, that can be daunting in and of itself, just imagining all the things that can go wrong in daily life. Now yours wants to go into a potentially hazardous occupation, and you can't be with her to protect her. Scarier yet! While some bad guys find it humiliating to be arrested, it's more humiliating to them to be taken down by a female, especially a little one, and they react more aggressively. A sad fact, but most bad guys aren't very nice anyway, especially during an arrest.
But having worked with several smaller-statured women in LE, I can tell you one thing.......I wouldn't have messed with any of them, because they had an aura of toughness about them that I never wanted to test. In fact, thinking about them, the term "She-wolf" comes to mind. Toughness is 95% mental, and as long as your little girl is aware of her surroundings, has a good partner or decent backup, and good dispatchers, she'll be fine. Since you raised her, I assume she's pretty sharp to begin with, and a good to very good shooter.
Daddy down, let her instructers instruct, and don't fear the unknown. If she gets into the academy and realizes she's not up to it, she'll tell you, or them, or both.
The only cops I ever worried about as partners or backup were the ones who somehow thought they were glorified social workers that helped everyone and were adored by all. When the feces hit the rotating oscillator, they were usually the ones standing flat-footed with their mouths open, who said later they didn't understand why those bad guys were trying to do those things. For some it was an epiphany, realized they were in the wrong line of work and got out.
Police work is the only field I know where you can be thrust into The Dark Place so often, and so unexpectedly. As long as she retains her situational awareness, she'll do fine. After all, you raised her right. Right?
Sorry for being so long winded, but I know how Daddies can worry about their little girls. I have two daughters, one I worry about, and one I don't. Both shoot well, but there's a lot more to cop-work than shooting. Being a good judge of people matters a lot more. Thanks for reading this, I feel better now!
