We want to make sure that a police officer cannot just go to the judge and argue that just because they believe a journalist has participated in a crime committed by a source that it's enough to have a mandate of inquiry. We would rather have more safeguards in the process and make the role of the judge, in layman's terms, stronger. Maybe Sébastien can argue the finer points of the law on this, but basically that's the gist of it.
