The huge story of the last week was the UK Guardian's revelations of massive data mining by the US government of Verizon and the outrage in its wake. Naturally, the paranoia is ramped up, as is the apologist rebuttal.  But one thing no one wants to talk about is this: What is to stop a government determined to "get" someone from simply fabricating electronically transmitted data? If someone is perceived as a "threat to national security" (for whatever reason), isn't it possible to create fake emails and texts?
Like a cyber version of a "throwdown gun "?
Not going all "line the walls with tinfoil, here comes the New World Order, Alex Jones is Christ incarnate" on you, but as such a thing is now doable, who's to stop it? Certainly not a rubber stamp  like the FISA courts. Certainly not the "benevolent nature" of politicians.
Something to consider when you are sanguine about "they're only protecting me".
