Would anybody like to predict and defend a probability above 0.00 that gov.uk will be able to meaningfully impede my ability use cryptography by 2020? Obviously politician's rhetoric, and to a large extent the law, have become unhinged from reality, so the odds of passing one more moronic, ineffectual law are a given: 1.0. But I'm asking someone to seriously state and defend even the slightest possibility that David Cameron might, in even the smallest sense, succeed. I can't.
