The problem for the doc wasn't the letter, it was never following up on it, and apparently not raising this issue any further.
It can happen, hears nothing in response to his letter and assumes yet again he has been ignored over Dank. If this is what he thought though, he should have either made a bigger noise or resigned. Silence unfortunately makes him complicit in the whole mess (and I mean unfortunately because everything you read indicates he is one of the good guys in footy)
That's absolute bullshit.
