As Inrng pointed out - we don't know what we don't know. It could be that things like this happen all the time and get quietly dropped because a satisfactory explanation is found. In which case Froome might be able to consider himself a bit unfortunate (but should not be surprised, because of his profile) that this one is being conducted in the open. Whinging about it being made public doesn't look good. Quite what is taking all this time isn't clear. Are Sky deliberately dragging their feet? I also read somewhere (can't remember where) that Froome is waiting to be called to Lausanne for PK tests, and the ball is actually in the prosecution's court (LADS/WADA/whoever it its).
