In the US stolen secrets that come to light are evidence - unless it is the government that stole them in the first place. The protection against warrantless search and seizure is a protection of the citizen against the government. Losing control of your secrets to the public at large making them no longer secret is a whole other thing no different than Sony accidentally publishing them themselves. In fact in this case Sony's own servers were doing exactly that.
So yes, Attorneys General across the US may be considered notified of any untoward activity that might be revealed in this evidence, compel Sony to cough up their own copies directly, and prosecute to fulfill their duty to protect the public. But they won't.
