And believe me, I've taken the TSA training. It's so not applicable to
freelance CFI's. Every answer seemed to be "Check with your supervisor".

I agree. It was actually much worse before AOPA informed the TSA that
indi CFIs exist. However, in some sense this just shows how spoiled we
are with the FAA. The FAA regs are written in "plain english" (in the
legal sense) and rules are mostly very black and white. The rest of the
fed gov't is not so straight foward and many rules are written by
intention. The TSA rules are a perfect example. They gave us vague
rules and then said "enforcement is not our objective, compliance is".
In other words "do as we want, not as we say".
