Well, that's the point, isn't it? People who are smart, who are using open-source solutions, such as Tails (and, you can mount TrueCrypt volumes in Tails), who access the Tor network via anonymous Wi-Fi and Tor bridges, who purchase their hardware (likely, tablets) anonymously and with cash only, who maintain the physical security of that hardware at all times and places, who wipe every trace of Windows from it, and perhaps, use an open source BIOS, pray, tell, how are TLAs/LE going to nab those people unless they dox themselves? Pretty unlikely; in fact, I do not know of any such case. The only attacks, so far as I know, have been against Windows, and everyone who is concerned about privacy is using Linux.
Point is that the US TLAs/LE will be back, once their "golden solutions" fail, and before you know it, it will be a crime to own a textbook on elementary number theory or even study such a topic. As Philip Zimmermann said, "If privacy is outlawed, only outlaws will have privacy."
Not a World that I care to live in.
