> I'm not convinced that there aren't large custom databases of shared private keys that can be used to grant individual, time adjusted master keys that would allow the FBI to enforce their 4th amendment duties while making it impossible for a single master key to be discovered and instantly break every devices encryption. To what end? Even if such a thing could be built, if anyone that wanted to hide something knew about this, they wouldn't rely on this encryption and they'd do something on their own (with a 3rd party app, or offline, or whatever). Encryption is a thing that can't be un-invented, which for some reason everyone that seems to side with the FBI seems to completely forget. Even 100 years ago, there was unbreakable encryption[1] (that could be done without computers). If Snowden taught us anything it's that you can't keep the existence of this type of thing secret forever. So, all you end up doing is making it easy to violate regular citizens' privacy, introducing a very real and very serious potential security risk if the database were ever to be compromised, and still not actually being able to decrypt any of the data you are actually (supposedly) trying to get at.
