neinei, if you watched the original documentary you will note that the head of their wada lab denied, flatly denied the accusations.
he denied it in a discernible english facing direct face-to-face questions from seppelt.
the fact that seppelt was given that opportunity (mind you, in moscow !!) ...to ask the accusatory questions, means to me that the direct evidence needed for wada to engage in the proceeding to withdraw the lab certification has long been, yes, g-o-n-e...gone are 'hot' aliquots poured down the sink, gone are the preliminary records, gone (read: neutralized) are the technicians and athletes able to confirm the story. recall, the whistle blowers stepanovs are, surprise-surprise, the refugees currently living in berlin, not moscow.
what i am saying, is that the matter seems long had been in the hands of lawyers who advised their bosses the day hajo requested a travel to moscow to interviewed them. plus, of course, the wada politicians who, if memory serves, had received a relatively generous contribution from moscow to the shrinking wada budget...
