the problem isn't "too much testing", it's having strict liability for trace amounts of substances which are present in the food and water supply.
People conveniently ignore the fact that the director of the Cologne lab called for threshold limits on substances such as this long before Contador's positive test.
No one has put forth a plausible explanation that the substance got in his system intentionally, unless it was from a blood transfusion. Get him for the blood transfusion (or, if there isn't evidence of that, let him walk).
This might be a sound choice if it were a consistent or widespread problem.
Aside from questionably relevant examples from other sports is there an abundance of false positives and or are trace amounts and questionable vectors a common occurrence in the current testing regiment?
The fact that the UCI and WADA requirements stipulate zero tolerance for banned substances in any quantity requires a Contador sanction.
If the answer to the question above is 'yes this is an intrinsic and recurring problem, the the rule should be reviewed and perhaps low thresholds implemented, until then - guilty as charged, unless he, his team and his lawyers can provide substantiated proof that the occurrence was unintentional.
In my experience if it walks like a duck and quacks like a duck, its a duck.
