But the same company literally tried to do a cover up?

At first, the OLG tried to refute the statistical findings. They denied there was significant lottery fraud, called the statistical analysis “simplistic”, insisted that the Edmonds case was an “isolated” one, and hired their own statistical consultants in an attempt to discredit me. The OLG CEO, Duncan Brown, even stated on television that “What was missing from the Fifth Estate’s numbers was the frequency of play of the retailers”, which was not only insulting but also completely false (as was clear from my report, which was available on the CBC website). This was the first time that my statistical work was opposed so vigorously and publicly, which made me feel rather uncomfortable (and also gave me a grudging sympathy for politicians, who are publicly criticised so frequently). However, the OLG tactic had very limited success, due to the sustained customer outrage.
