Mr. Bard, there is software available out there to track PIN-to-PIN communications. Some financial institutions and government agencies do use this software to track this material, these communications. In a recent CIBC court case, these records were subpoenaed for that purpose. Why have we not, in the environment we are in--government--tracked these communications? Because it's an open forum for people to communicate that would circumvent any freedom of information or ATIP request.
