But those types of actions are rare.
Plus for certain kinds of investigations, it would go against the court order to go public. I don't want to defend apple here but this is an American law enforcement problem, I'm certain ms, google and others have provided info to the government that would anger many and there are probably a lot of companies that do it without a court order... Trying to be good citizens.
Why the hell was that info on a laptop?
But again, if that were the case then it would be related to anti-terrorism efforts. Well I hope it would be. The FISA court exists for that reason (mostly).
I guess my paranoia depends on how much I trust the government :)
