The Wuhan National Biosafety Laboratory is a “Cellular Level Biosafety Level 4” facility, which means it has a high level of operational security and is authorized to work on dangerous pathogens, including Ebola.
Those entering the level 4 lab use airlocks and protective suits. Waste, and even air, is heavily filtered and cleaned before leaving the facility.
Milton Leitenberg, an expert on chemical weapons at the University of Maryland, said he and other analysts around the world had discussed the possibility that weapons development at the Wuhan lab could have led to the coronavirus outbreak in a private email chain but that no one had found convincing evidence to support the theory.
China has a BL3 lab that has ‘lost’ SARS more than once...
That’s another way of saying unsupported, but not debunked. There’s a vast difference between this theory and the JFK assassination thing. The US is an open society, and people who might have been involved in pulling levers in the background can disclose things to reporters without anyone finding out who they are. Whereas China is a country where disclosing something the government doesn’t want publicized can get you killed on charges of espionage/treason, because the government will simply torture the journalists involved until they give up their source(s).
It’s the only theory that makes sense.
