You did ask it to be proven.
Done.
Yes. Fair enough. His father does look like the touchy (can't see touches face, but similar beard).
Let's just say for arguments sake we can confirm it is his father.
Everything else I have argued is still true.
This isn't some cheating scandal because NSW referees appoint refs AND additionally I have completely broken down every potential infringement Barker could have been called for, and its evident that there should never have been a penalty blown in first place.
The right call was made and the only thing that is up for debate is whether play should have died when whistle was blown (which would have resulted in Barker having another opportunity to score 5 metres out, which probably ends in a Barker try anyways), or whether because the whistle was blown when Barker player was in process of diving for line, it is reasonable to deduce that a try was CERTAIN and hence try is good. And as I said earlier
ref made this call, not assistant ref.
This is merely a really bad look, but the right call was made in the end.
