I guess it depends on WHICH law enforcement. NSA and related agencies - would not discount it for a second. Regular police would probably need a good reason to spend the resources, and the case would probably need to hit the "right" department that will take it through.
But a lot of the revelations are them not actually breaking the encryption. More man-in-the-middle, stealing keys, playing with implementations, spying etc. The law enforcement that manage to get the scumbags servers can also get the keys to infected users, which aids in decryption.
basically you just can't believe anything you hear.. trust is fundamentally gone, everywhere. from the Ma and Pa shops, local grocer, fuel stations, corporations, gov, media.. I challenge anyone to provide a single instance of some entity that is fully trustworthy.

I think they are getting better at producing really bad malware that is worse and worse for us public
