I've a feeling that some of the frauds are going to start babbling about making a 'principled' stand and refusing to sign on the grounds of human fights infringements blah, blah,blah. It will, of course, be entirely unrelated to the fact that they are the ones under suspicion. When an irregular sample is later revealed, they will start bleating that it's all part of a witch hunt for refusing and that they've been set-up as a punishment by the mendacious and vengeful UCI.
