At this point I want to see the evidence. Is there no concrete records?

Also what Billing said is true.

Regardless, the case at hand is clear and unambiguous: Jonny did not
follow the exact steps for claiming a draw, and the operator's choice
to continue the game was legal.  Those who have criticized the ICGA
on this matter should rethink their position.

You say no, but this is a very seasoned TD. I concur at this junction.
