At least since the aftermath of September 2001, western governments and intelligence agencies have been hard at work expanding the scope of their own power, while eroding privacy, civil liberties and public control of policy. What used to be viewed as paranoid, Orwellian, tin-foil hat fantasies turned out post-Snowden, to be not even the whole story.
What's really remarkable is that we've been warned for years that these things were going on: wholesale surveillance of entire populations, militarization of the internet, the end of privacy. All is done in the name of "national security", which has more or less become a chant to fence off debate and make sure governments aren't held to account – that they can't be held to account – because everything is being done in the dark. Secret laws, secret interpretations of secret laws by secret courts and no effective parliamentary oversight whatsoever.
