Good Question

The primary qualification for "acting up" as an FTO appears to be that you are on the "Sergeant Eligibility List" for promotion, meaning you had to score as well as the dumbest clout hack that Special Ed wants to promote, so somewhere in the vicinity of 57%. If you scored 58%, you might never get promoted legitimately, but you can qualify to teach someone how to be the police.

Is there any actual additional training? We don't plan on finding out, so we'll need to hear from someone in the process. Because teaching isn't easy. You have to make the material interesting and applicable to real life situations. We can do that with a blog, but we aren't being modest when we say we doubt our ability to teach it to another human being. Sure, we can help someone fill in a parker or write a mover and our case reports would win screenwriting Oscars.

 But the stuff that only comes with experience would be far harder. The only way to get that experience is to ...well, experience it. And keeping an eye on a green rookie (or two) along with the situation we're in the midst of, and actually use it as a learning experience while it's going on? Not our cup of tea.
