It’s absurd to consider. The Witness is not some cartoonish lair of wickedness with a big red button on a pedestal marked DO NOT PUSH . It is a network, infinitely nested and protected, millions of lines of code resting on millions of lines of code, the ecosystem of interrogation and surveillance almost perfectly adapted to absorb what is wanted and keep out what is not. There is no way anyone could devise a defence, any more than you can wave off an army or a neutron bomb.
