I was speaking to an Austrian friend a few weeks ago... He knew all about it
I think you may have quoted the wrong post in all the excitement.
But just to elaborate on the post you did quote, HCW had to go public last June, he had little choice. I'm sure it was a last resort because it's a revealing of his hand in and of itself.
His evidence is apparently screaming at him, the grown ups have probably intimated that it's compelling, but just eek out some corroboration.
I doubt he would have envisaged his public appeal for information would yield nothing (otherwise there would have been action by now). Couple this with the less than outright backing from SY and it's all a bit embarrassing.
It was always a shit or bust call....ID the caller and it's Christmas, get nothing of substance and it's bin bag for Hans.
His last vestige of hope is that the prosecutors roll the dice with what they have and hope CB sings like Gladys Knight - and I would buy tickets to watch that go down.
