dank?
You mean the same Dank who could easily have spoken up and cleared up this whole mess a long time ago, or heck, just produced the permission (letter/email) from none other than the governing body to use the substances in question in the first place?
If he's got nothing to hide, why would he instead allow his reputation to be completely ruined, and maintain that he will risk the few thousand $'s a day, and refuse to cooperate with the investigators should they come knocking? Principles? Unlikely, just ask Sandor Earl. Because Dimwittio was disrespectful to him in the media? Because if he sings like a canary he might end up in the harbour in a pair of concrete shoes...?
Until they talk to him everything is still up in the air.
For mine, this investigation is dragging on at least in part because once ASADA choose to use their new powers under the legislation, it's go time. There is no point going in half-cocked, since I assume that they would still need to make an application to compel him to talk (due to the punitive aspect should he refuse), and there would be a burden of proof associated with that.. By the time they speak to Dr Dank (and they absolutely will regardless of how much he pounds his chest in the press), they will know all the right questions to ask (and for the most part what the answers SHOULD be).
Stay tuned, as a poster alluded to earlier it's not over until ASADA/WADA/whomever come out and say one way or the other that it's case closed.
