That's correct. Sometimes the diaspora have given testimony behind closed doors to parliamentary committees. Often, they've talked to government officials.
There's something called the Canadian coalition on human rights in China, a body made up of the leaders of many of these diaspora groups. What they have to reveal is shocking and very concerning as to how they and their families are treated. They are threatened through their families back home. To go public, as David Johnston wants them to do, would put them at further risk.
What we've seen is that, when he talks about public hearings, it's the diaspora that he puts front and centre. In addition, he's talked about having people like the intelligence and security experts you've heard from today, who have given testimony. We've heard them in this forum; we've heard them in many forums.
I think it's more important to get to the root of what's happening in parliamentary electoral interference and in the other systems of interference that they have in our society.
