Madam Chair, I think the simplest explanation for that, in my view, is that usually in the case of a whistle-blower, there is some element of disclosure of wrongdoing on the part of the government. In this case, nobody's really alleging that there's wrongdoing. People are alleging that the government should have done more. It's not quite the same thing as wrongdoing.
Just because you get a security clearance, it doesn't mean you have the right to disclose information that's within your charge. Whoever the leaker is, they are, in point of fact, probably guilty of offences against the Official Secrets Act—actually, not the Official Secrets Acts, as I'm going too far back in my time—but the security of information legislation. They're in violation of the legislation and should be prosecuted.
