I have a question on the precedent set for whistleblowers giving evidence or testimony in private session. Other than Sergeant McCabe, have there been other whistleblowers? If so, can we have the details? This is the first term that some members have been on this committee. I would like, if at all possible, to see the transcript of that evidence. Is a transcript available when a meeting is held in private session?
