What it might do is make the 3 researchers getting sick in the lab in November less interesting..
The "alleged 3 researchers".
names have never been given by those claiming to know this... . Source for the information has never been supplied.....
The Australian working in Wuhan lab at this time, never heard anything about this...
So until you have some corroboration for this claim please be cautious.
China should cooperate. But they won't. There is a long history of China's interactions with the west, where they bent to the will of the west and got screwed over. They have always resisted international standards, and international law, and what they see as interference in the domestic affairs of China.
And that includes decades before the Communists came to power. You see it reflected in their attitude towards international trade treaties where they accept that which will profit them and resist that which they see as "interference". One need the entire world to insist on treaty obligations or China plays one off another and does what they want. (Why backing out of Asia Pacific Trade pact was a huge mistake.)
There is nothing unusual about them resisting scrutiny in this matter . And thus should not be taken as an indication that there was a leak.
Indeed their cooperation in the initial identification, after a couple of weeks of low level beauracrats bungling the response, was exemplary. Remember who gave every body the DNA sequencing that allowed the rapid development of the vaccine. And it should be noted that scientists at Wuhan published their research regularly...
If the Covid 19 virus was around longer than originally suspected, as the Italian research shows, its likely we'll never know definitively where the virus came from. We only know that "super spreader" events lead to rapid spread. In China the wet market. In Italy, probably contact with health care providers at old folks homes and etc.
I find it hard to focus on conspiracies with only very limited plausibility when obvious answers with accepted high probability exist. Especially since even if the definitve answer were known it would in no way effect the current situation.
There has to be a nefarious purpose behind the spread of these conspiracy theories". And that purpose is to deflect from the failings of the response to the virus.
And not just initial failings. The death rate in the US continues to climb as vaccination rates plummet and "freedom fetishists" refuse to follow public health protocols.
So, having the Chinese to blame, both distracts and confuses the public .... Who seem to be easily distracted and confused.
