The initial outbreak cases were clustered around the wet market, not around WIV, and the cases weren't linked to WIV. There was a documented lab leak with SARS-CoV-1 and it killed the affected researcher's mother. That'd the kind of thing you expect to see in a lab leak. Instead you see a cluster of cases that look exactly like it spilled over from the wet market.

And there's zero evidence to support the lab leak. All the research they were doing on live virus was based on SARS-CoV-1. You can't get SARS-CoV-2 out of that. And while they sequenced RaTG-13, there is no evidence they ever had live virus, and RaTG-13 is still around a thousand mutations and a few decades of evolution away from SARS-CoV-2.
