Human frailty is to blame for the culture of drugs cheating and corruption within Russian athletics, says World Anti-Doping Authority Director General and New Zealander David Howman.
Russia could be banned from next year's Olympics in Rio de Janeiro, after a damaging WADA report today uncovered evidence of bribery, and government-backed corruption, doping and the hiding of positive tests within Russian athletics.
Howman believes such a culture of cheating and deceit was able to exist simply because those involved in athletics and government administration are vulnerable to temptation and corruption.
"It happened because people can be corrupted and we deal with a program in anti-doping where we rely very much on human beings," Howman told The Paul Henry Show.
"It's not just a process or set of rules, and sometimes human beings let us down and this is what's occurred on a big scale in Russia."
