The world has been told by the FBI that North Korea is behind an unprecedented infiltration into Sony. Recent comments made by President Obama promise a federal response to these actions, but fall short of calling them an act of war.
With precedent, we can expect the US to respond in the form of new legislation designed to mitigate future cyber incursions. We also know that this event will serve as justification for future actions, both offensive and defensive.
It should therefore be reasonable to request that the details pointing to North Korea be made available for public scrutiny without hesitation. An intelligence failure involving this much data would be impossible to defend should the need arise.
