Memo to UCI; What the hell are you doing?

I don't understand the logic of destroying a man's career/legacy without definitive, conclusive, irrefutable proof.

UCI source says some Landis testosterone exogenous: "Some of the testosterone found in Tour de France winner Floyd Landis' 'A' sample is from an external source and not his body's, The New York Times reported on Tuesday, quoting an unidentified UCI official."

What is wrong with taking the time and the steps to do the test correctly and release the results then?
