UKAD: suspension of boxer Larry Olubamiwo represents success of anti-doping officers

The heavyweight boxer Larry “War Machine” Olubamiwo administered some anabolic steroids, HGH, IGF-1 and other doping preparations during 6 years. However several tests have been conducted earlier, he was caught only in January 2012. After a fight against Sam Sexton Larry Olubamiwo tested positive for forbidden medications. Metabolites of steroids were not found in his sample. The boxer tested positive for EPO. EPO is a blood boosting medicine.
Prolonged usage of prohibited medicines by Olubamiwo was a real embarrassment for the United Kingdom Anti-Doping. Andy Parkinson, the CEO of the UKAD, tried to prove that the ban of Olubamiwo for administration of 13 different prohibited preparations is a real success of the UKAD in the struggle against doping.  
Andy Parkinson confirmed that it was an unusual case. The boxer used steroids and other related preparations for long period of time without fear to spoil his health, career and reputation. He was sentenced to 4-year ban.
But the alarming aspect is following: Olumamiwo could avoid detection for prolonged time, despites great efforts of anti-doping officers to “clean” sports from administration of doping medications.
Olubamiwo was caught just because the UKAD was informed by the United States Drug Enforcement Administration (DEA) that he was implicated in an investigation connected with illegal sale of anabolic steroids and other performance-enhancing drugs in the US. Then the UKAD conducted a test that resulted in positive results for EPO.
Robert Smith, the General Secretary for the British Boxing Board of Control, supported the statements of Andy Parkinson about efforts and success of anti-doping agencies. He noticed that the case displayed that cheating couldn’t be hidden.
What is your opinion about the case? Do positives for EPO and the ban of Olubamiwo show that anti-doping officers succeed? Or does the case demonstrate that anti-doping policy is not suitable?
Every person can make own conclusion. But it is clear that the sportsman could take numerous forbidden substances for six years without being caught by anti-doping officers.
