I'll tell you what the biggest problem is, based on my analysis. I don't know whether you are aware of operation Scorpion, a major investigation carried out by the Quebec police in 2002. During this police operation, certain people testified. I'm thinking in particular of one victim who said that she had over 100 clients, including several politicians. The victim spoke to the police, but it never went to court, unfortunately. She couldn't appear as a victim for all sorts of legal considerations that I won't go into here.
In any event, the key problem is still providing evidence. When people in a position of power are involved, fear creeps in once the investigation begins. Until there is enough evidence to show that there's no reasonable doubt, it's very difficult for the police to move forward, particularly as, in Quebec, it's the attorneys who determine whether or not charges will be laid.
It's therefore difficult for me to suggest any recommendations.
