Yes - except diplomats, journalists, doctors, as well as conversations between people in person are all "warrant-proof", and therefore "above the law" as Feinstein calls it.
As Zdziarski also says in his post below , the 4th amendment doesn't grant the U.S. government anything. It tries to restrict the U.S. government from overreach. It says only upon probable cause can the government request personal information, but it doesn't say the government MUST get that information and in a format that's intelligible as well.
But when the U.S. government has started interpreting the Constitution however it gives it more power, even saying that your "emails" can be obtained without a warrant because they've been "opened" , or when it believes that spying on millions of people at once is "relevant" to a specific investigation (3-hop spying) then it's no surprise that they also believe the 4th amendment gives it the power to require the data in an intelligible format.
> No new collection authorities. The bill does not create any new collection authorities for the government to obtain communications. The bill simply requires covered entities to ensure that the government’s lawfully-obtained evidence is readable—so that law enforcement can solve crimes and protect our communities from criminal and terrorist activities.
Well, that's a lie. Until now, only "covered entities" under CALEA could be forced to facilitate spying. Now everyone else can be forced as well, including open source developers. I'd say that's quite an expansion of its "collection abilities", no?
