ARGUMENT: Lab-leak theoryThe Lab-Leak Theory: Evidence Beyond a Reasonable Doubt

Published 5 June 2021

In the justice system, where the most exacting evidentiary standards are applied, Andrew McCarthy writes, the requirement is proof beyond a reasonable doubt, not proof beyond all possible doubt. “There is no proof beyond all possible doubt.” And investigative journalists have chronicled for months what must be considered “proof beyond a reasonable doubt that the coronavirus pandemic was generated by an accident — a lab leak, a not-uncommon mishap in medical research conducted by fallible human beings — at the Wuhan Institute of Virology.” He adds: “Unless and until China comes forward with convincing evidence that the lab-leak theory is wrong, the position of the United States and the world must be that China is culpable.”

The COVID-19 pandemic has caused nearly 4 million deaths globally (now closing in on 600,000 in the U.S.), in addition to geometrically more instances of serious illness, trillions of dollars’ worth of economic destruction, and incalculable setbacks in the educational and social development of tens of millions of children.

“We can no longer afford to be wrong when it comes to the origin — the generation by regime-controlled Chinese scientists, almost certainly by accident” — of this pandemic, Andrew C. McCarthy writes in National Review.

McCarthy, a former prosecutor, notes that prosecutors are in the business of proving stuff. “Every good one will tell you that the best case is a strong circumstantial case. It is the most airtight and least problematic kind of proof.”

He adds that in the criminal justice system, “where we apply the most exacting evidentiary standards, the requirement is proof beyond a reasonable doubt, not proof beyond all possible doubt. There is no proof beyond all possible doubt.”

What NR’s Jim Geraghty has chronicled for months is proof beyond a reasonable doubt that the coronavirus pandemic was generated by an accident — a lab leak, a not-uncommon mishap in medical research conducted by fallible human beings — at the Wuhan Institute of Virology. Ditto the important work of Nicholas WadeVanity Fair’s Katherine Eban, our own Michael Brendan Dougherty, and a few intrepid others.

Lab accidents are common, and have been known to spawn infectious diseases (including the escape of SARS1 from the Chinese National Virology Institute in Beijing “no less than four times,” according to Wade). WIV scientists were conducting gain-of-function research on bat-based coronaviruses, in particular their capacity to infect humans. The bats in which are found closely related (but, importantly, not identical) viruses do not inhabit the vicinity of Wuhan — they are nearly a thousand miles away from that densely populated city and have limited flight range. The likelihood of naturally occurring interspecies transmission (outside a lab setting) is infinitesimal. The lab conditions in Wuhan were insufficiently safe — grossly so, it appears. Several of the lab’s researchers fell ill (at least three severely enough to be hospitalized) right at the critical time, in autumn of 2019, before the first identified case of infection with SARS-CoV2, the virus that causes COVID-19.

He concludes: “Unless and until China comes forward with convincing evidence that the lab-leak theory is wrong, the position of the United States and the world must be that China is culpable.”
