How indeed

I've already provided a partial answer. But it's still worth highlighting Dan Gardner's pointed questions on the disturbing turn taken by politicians on both sides of the border over the past decade:

How is it possible that in this most civilized of nations, in 2010, a member of Parliament felt the need to raise (the question of murder as a matter of policy)? And while we’re asking rhetorical questions that would not need to be asked in a sane world, how is it possible that the Republican party has so completely embraced aggression and brutality that almost all its leading figures feel the near-drowning of suspects is a valid interrogation technique and imprisonment without charge or trial is a legitimate practice that should be expanded? Why is it that most people in the United States and elsewhere are not disturbed in the slightest that, despite abundant evidence, American officials who apparently committed heinous crimes in the war on terror will not be investigated and held to account, while Wikileaks founder Julian Assange, who apparently did nothing illegal this week, is hunted to the ends of the Earth? And how in hell is it possible that when a former president of the United States of America admits he authorized the commission of torture — which is to say, he admits he committed a major crime — the international media and political classes express not a fraction of the anger they are now directing at the man who leaked the secrets of that president’s administration?

I marvel at that paragraph. It would have been inconceivable even 10 years ago. Murder treated as a legitimate option in political discourse? Torture as acceptable government policy? No, impossible. A decade ago, it would have been satire too crude to be funny.

And yet, here we are.
