The problem though, and the point people are missing (I think, though maybe I'm giving Holder too much credit) is that when they do get a warrant, they still can't access the data. Again, maybe I'm giving them too much credit, but law enforcement should be able to get a warrant and then access that data, through a legal search and seizure. At least the way it's being reported, with iOS 8 even if law enforcement brought a legal warrant to Apple, Apple wouldn't be able to decrypt the data. Won't be long before Google and Microsoft follow suit.
I know, I know, the Slashdot response will be "but NSA!" So be it.
