As it will take years for culpable parties to retire, I once feared that a full generation would need to elapse before we recognised lockdowns for what they were: the biggest public health debacle in history. Yet everywhere I turn lately, still another journalist is decrying the avoidable social, medical and economic costs of this hysterical over-reaction to a virus, while deriding lockdown zealots for having vilified sceptics of a policy that may well end up killing more people than it protected. The Covid revisionism is welcome – though it’s a good deal easier to publish these opinion pieces now than it was two years ago, and I speak from experience.
