Harper's 'Let's not and say we did' Mulroney inquiry

Harper's "hand-picked independent third party" advisor has regretfully noted that his mandate "does not allow him to recommend that a public inquiry not be held" at all into the Mulroney Schreiber scandal, but that doesn't preclude him recommending a very narrow limited one behind closed doors.
Right off the top David Johnston suggested it shouldn't be fully public, and

CP : "Johnston's limited terms of reference do not include the $2.1-million libel settlement Mulroney negotiated with the Canadian government in 1997 while allegedly misrepresenting, under oath, his relationship with Schreiber.
And they would likely keep an inquiry from following the $10 million in "grease money" that German court records suggest was given to Schreiber by Airbus International to bribe Canadian officials in the 1980s."

Chronicle Herald : Also, it "should not examine the business dealings of Brian Mulroney’s friends who profited from an agreement the government signed to build an armoured car factory at Bear Head in Cape Breton."
- the one that was never built.

or the Muldoon's tax records.

Yesterday Con House Leader Peter Van Loan told the Commons - surprise! - the government intends to follow the valued advice of their hand-picked advisor, and Mulroney has graciously said in a statement that he would co-operate with the inquiry "within its mandate" recommended by Johnston.

So what the hell is left for the inquiry to do exactly?

Conservative MP Russ Hiebert : "The conclusions that he [Johnston] came to were very similar to the recommendations that we provided in our minority report, basically acknowledging that there was no wrongdoing, and that if there was going to be a public inquiry, it should be focused on the transition that high public office-holders make to private life."

That is not even fucking close.
What Canadians would like to know is why they paid Mulroney $2.1M in libel fees because he didn't care to talk about $10M in grease money or the $300,000 he has since admitted to personally receiving from Schreiber.
I think they'd also like to know that their government is not so irretrievably broken or crooked that it can't handle an open public inquiry.
