1. there is no reason to be pedantic about the language around QI. We are not in court, so you're not impressing anyone with your "actually" non-sense. Any reasonable person can infer that I was talking about cases in which QI would be used as a justification to absolve the officer of responsability.

2. Your first rebuttal point reinforces my point, in practice there are very few cases that result in QI being used w.r.t. teachers.

3. I think most of us can agree that QI shouldn't apply to teachers or officers or any other State actor and is legal non-sense created by junk judicial interpretation.
