If you look at the threshold for a criminal act, you need the right evidence to get the legal documents to allow you to do a production order or a search warrant to eventually lay the charges, if there are charges to be laid.
I must say that the Ethics Commissioner does have power with regard to his ethics review. If he does come across any criminal matters, he's to refer them to the RCMP. In this case, the Ethics Commissioner, who had access to more information than the RCMP, did not refer anything to us.
