I have been trying to figure out whether we're in the right line of questioning or not, so let me just read this from O'Brien and Bosc, so that it's very clear for everybody:
Particular attention is paid to the questioning of public servants. The obligation of a witness to answer all questions put by the committee must be balanced against the role that public servants play in providing confidential advice to their Ministers. The role of the public servant has traditionally been viewed in relation to implementing and administering government policy, rather than the determination of what that policy should be. Consequently, public servants have been excused from commenting on the policy decisions made by the government.
That's why we've been.... We're kind of balancing on the head of a pin here.
