I thought all gain-of-research work was illegal in the U.S. That's why Fauci outsourced the UNC work out to Wuhan.
The "researchers" took a spike off of the omnichrome variant and implanted it somehow on the original variant. Assuming this can even be done, that would mean they had isolated samples of both variants -- something no institute in the world has.
If they only have the variants in cell cultures, that means the mice were injected with a the poisons, serums, and cellular debris from not one toxic soup, but from two. Who wouldn't die?
This is suspicious as all get out.
