Mr. Chairman, my understanding is that Sergeant Frizzell, as an experienced police officer, has had to respect all of the statutes and the jurisprudence that deal with police work throughout his career. That's what he's used to and that's what he is bringing, as his custom and habit, to this committee.
The rules in this forum are somewhat different. If the committee demands the information, my understanding is that under parliamentary law the witness has to reply. In that sense, parliamentary privilege trumps the professional obligations, even those derived from statute and jurisprudence.
