The article refers to statements provided by Dany Shoham, a former Israeli military intelligence officer who holds a doctorate in medical microbiology, and served as a senior analyst with Israeli military intelligence for biological and chemical warfare in the Middle East and worldwide from 1970 to 1991. “Coronaviruses (particularly SARS) have been studied in the Institute and are probably held therein”, Shohan reveals, as has anthrax, adding that “certain laboratories in the Institute have probably been engaged, in terms of research and development, in Chinese [biological weapons]. Work on biological weapons is conducted as part of a dual civilian-military research and is “definitely covert.”

A) Here we go again. Special insight from our Israeli allies.

B) The Chinese aren't stupid. Biological warfare is waged on your enemies.
Does anybody think that an infected bio weapons employee would go shopping in an open market for groceries, etc.
In 2012 an earthquake hit China and damaged poorly constructed schools killing many children. Grieving parents lost their only child and didn't complain to the foreign press, cause "it could bring shame on China".

I think it's unlikely that these guys would make a stupid mistake like this.

C) It's awfully convenient that the epicenter of this virus was established as quickly as it was. It's almost as if there was fore foreknowledge. The location appears to be known before the virus was identified by name.
When Ebola hit Africa it took weeks to estimate the epicenter.
