This has nothing to do with the corona virus strains we are currently dealing with, and more importantly, there has never been any credible research proving that Covid was made in a lab. The only paper that got any traction suggested it was non-manipulation based gain of function research, but that was disproved only a few weeks after the paper's release as well. I know we all want to know where it came from, but the odds against us ever having actual evidence of it being from a lab are virtually zero. And no, rejected research proposals do not constitute proof of anything.
If I was near a bank robbery at the time of occurrence, it does not count as evidence that I did it. Not even if I have a history of robbing banks. It must be combined with other, stronger evidence (I was inside the bank, my fingerprints were there, I was caught on camera) to build a case.
