The recent arrest of someone behind Silk Road is in the news today, he was arrested in a San Francisco public library. A couple of background articles here and here.
To what extent, if any, did staff and/or admins have in assisting law enforcement agencies in arresting this programmer? Did they voluntarily cooperate, or was it a legal requirement to cooperate under US law?
An answer from some authority saying Stack Exchange is not able to discuss the issue with users is also acceptable to me.

should be a federal offense.
