...which was before I started officiating. Am I expected to know all these POE from before I started reffing?

I happen to know that POE because I am on this Forum, no other reason. If the NFHS was so dead-set on this being 100% a technical for taunting, every time, then perhaps they should add it to the current year rules/case book so I can know for sure. I believe I'm on shaky ground when I start calling stuff based on what the rule book said 6 years ago.
