This is exactly why tennis/ITF/ATP have a serious conflict of interest on their hands, and why would consider not making cases like these public. i.e Agassi's positive(doesn't matter the substance) being swept under the rug.
The same people in charge of busting their stars for potential cheating, are the same people in charge with Marketing the current stars.
