The question about Mike Duffy

There are two possible ways of looking at Senator Duffy's behaviour in the Senate regarding $90,000 in housing allowances.
Here's the Harper Con way:

The Harper government is praising Conservative Sen. Mike Duffy for showing "leadership" in the Senate expenses scandal.

That's because he paid the money back, I guess.  But here's the Liberal way of looking at it:

But Liberals say the Conservatives are protecting one of their own, tipping off Duffy about ineligible per diems and whitewashing a report on his invalid housing allowance claims.

Gee, which way is the right way to look at this? How can we ever possibly tell?
Well, when in doubt, I suppose we should look at what people actually do rather than what they say.
Yes, Duffy did pay back a whack of undeserved money.
But he kept signing those supposedly "confusing" primary residence declarations month after month, every month for three years.
And then he avoided answering questions about it by ducking through a hotel kitchen after a speech.
Some leader...
