The Lab Leak Theory

Donald G. McNeil Jr. on how he learned to love the lab leak theory. An excerpt:

But later he learned of studies with Dr. Shi’s name on them showing that work he considers dangerous had been done in level BSL-2 labs, which he considers highly porous to leaks, not just in 2016, but in 2020.

“That’s screwed up,” he said. “It shouldn’t have happened. People should not be looking at bat viruses in BSL-2 labs. My view has changed.”
