I don't know why it is. I think this is an issue that they obviously don't want to talk about. There's reason they haven't called a public inquiry, which would have been a very easy thing to do. There's a reason they drag their feet and filibustered this committee so that Katie Telford, the Prime Minister's chief of staff, wasn't able to attend. There's the fact that they lash out at media that ask them questions and claim that CSIS is wrong, only to, of course, backtrack.
Of course, on the briefing note that said MP Chong's family was targeted in Hong Kong, the original answer by the Prime Minister—and he was very hostile about it—was that it never made it out of CSIS. Well, now we find out that it actually made it out of CSIS and one of three national security advisers would have received it and not actually read the brief.
I'm not sure why. I guess they are hostile because there's obviously something they are hiding.
