This Is Not Necessarily Evidence of It Being a Bioweapon

 But it might evidence that "gain of function" research escaped the lab in an accident, which neither the CCP nor the NIH would want to admit. 

The genetic structure of SARS-CoV-2 does not rule out alaboratory originSARS-COV-2 chimeric structure and furin cleavage site might be the result of geneticmanipulation

Abstract Severe acute respiratory syndrome-coronavirus (SARS-CoV)-2′s origin is still controversial. Genomic analyses show SARS-CoV-2 likely to be chimeric, most of its sequence closest to bat CoV RaTG13, whereas its receptor binding domain (RBD) is almost identical to that of a pangolin CoV. Chimeric viruses can arise via natural recombination or human intervention. The furin cleavage site in the spike protein of SARS-CoV-2 confers to the virus the ability to cross species and tissue barriers, but was previously unseen in other SARS-like CoVs. Might genetic manipulations have been performed in order to evaluate pangolins as possible intermediate hosts for bat-derived CoVs that were originally unable to bind to human receptors? Both cleavage site and specific RBD could result from site-directed mutagenesis, a procedure that does not leave a trace. Considering the devastating impact of SARS-CoV-2 and importance of preventing future pandemics, researchers have a responsibility to carry out a thorough analysis of all possible SARS-CoV-2 origins.
