I would say you've identified the significant challenge with respect to the sharing of information, be it biometric or otherwise. Agreements are essential, and they have to be put in place with Canadian values in mind with regard to privacy and who gets to access the information. I don't know what I could provide you in the way of definite assurances. The Canadian Police Information Centre exchanges biographical information with the United States and their NCIC system, which is their equivalent to our CPIC, so there are controls in place to ensure that information goes where it is intended to go and no further. However, our countries do not audit each other. That's the current arrangement with the biographical exchange of information.
