Parce que ceux qui sont citoyens canadiens pourraient donner lieu aux mêmes inquiétudes que ceux qui font actuellement l'objet d'un certificat de sécurité, mais les citoyens canadiens ne peuvent, eux, être assujettis à un certificat de sécurité.
There can be citizens who may raise the same concerns as those people who are currently under security certificates, but because they're citizens they cannot be made subject to a security certificate. So what is presented to the Canadian public all the time is non-citizens, immigrants, and refugees who are presented in the media as being the potential threats to Canadian security.
