Follow the money. This will fail for the same reason the Clipper Chip failed. It was/will be bad for American business and destroy American jobs. NOBODY outside America is going to buy tech with FBI backdoors. Apple, Google, Microsoft, Facebook, and nearly every other tech company, representing trillions in market cap, and billions in campaign contributions, are lined up against it. They can not only buy as many politicians as they need, but they can also use ad dollars to go direct to the people. Apple and Facebook are way better at manipulating public opinion than the FBI, and they have far greater resources.
