""" Since SHC014 could not be success fully isolated, a recombinant virus (rWIV1-SHC014S) was constructed based on the WIV1 backbone with the replacement of SHC014S gene, as described previously (Zengetal.,2016). The S sequence of SHC014 was amplified with primer pair (F-SHC014-Bsa I, 5′-AGTGGTCTCAACGAA-CATGAAATTGTTAGTTTTAGTTTTTGCTAC-3′ and R-SHC014-Bsa I, 5′-TCAGGTCTCAGTTCGTTTATGTG-TAATGTAATTTGACACCCTTG-3′), digested with BsaI, and inserted into an artificial bacterial chromosome along with the other viral cDNA fragments."""
One analogy for developers: Bad persons are using git to develop ransomware, and company X is also using git, therefore company X is developing ransomware.
Which ever way you frame it, it is correlation, not causation. Poor evidence at best.
Out of all the wet markets that serve that much population, the coronavirus just happened to appear at the market nearest to the lab studying coronaviruses. To have such a coincidence is like winning the lottery.
It's not evidence, sure, it's correlation at best. But this alone should make you investigate that lab much much better, it should be the first possible cause you research.
But looking at the lab first might be hard if you have a severe conflict of interest https://www.taiwannews.com.tw/en/news/4119101
I am not saying this to "make China pay". After all, the US itself was sponsoring coronavirus research at that lab. But we should establish a worldwide safety standard in dealing with such research, and establish periodical inspections. Just like we do with Nuclear power plants, only better.
