Teflon Lance

I was amused imaging the dismay that J must have felt to learn that the US government has closed their investigation of Lance Armstrong without charges.  So to recap we're going on like 12 years where governments and agencies of all kinds across the US and Europe have tried their damnest to bring down Armstrong, and continue to come up empty.  So my question is, considering the magnitude of effort to find the evidence, the money and power of the people involved, and the continued failure, when do we call it quits and leave him to his life?  If all of these people and organizations cannot find enough to make it stick, then maybe it just isn't there.
