Let's make an assumption . . . assumption #1 is that the testing regimen and procedures for handling samples gets cleaned up and handled in a legally- and scientifically-responsible way. (I'm not entirely sure that's being done yet.) Assuming THAT happens . . . what should the penalty be when a rider is caught doping, using banned substances, etc., etc., etc.?
Obviously, the two-year ban is not enough to deter anybody.
