Britain’s authorities are sinister because they are turning on fundamental liberties, without which a free society cannot function: freedom of speech, freedom of the press and the right to protest. They are preposterous because they are wasting their time and our money on crimes that turn out not to be crimes on closer examination. Instead of keeping a steady head, they pander to popular hysteria and round up despised minorities: left-wing demonstrators, tabloid journalists and the politically incorrect users of social media. It is as if the criminal justice system has become a vast job creation scheme for cops and briefs. Or perhaps the better comparison is with the Aztec gods, who needed a steady flow of sacrificial victims to satiate their hunger. It certainly feels that way when I talk to honest men and women caught in the law’s maw.
