Theory 2 - Lab Origin

Lab-Origin

Someone working for an Wuhan lab became infected with an engineered version of RaTG13 (or similar) then spread it into the community.

Evidence so far:

• An unprecedented, super-contagious coronavirus breaks out in Wuhan - right-next-door to a lab that was engineering super-contagious coronaviruses.
  
• Exhibition of weird name-calling behaviour from the world’s top experts when questioned as to whether it may have escaped from a lab.
  
• RaTG13 (aka BtCoV/4991), collected from the Mojiang mine, was held at WIV, as were samples from the infected lungs of miners from the 2012 Mojiang incident.
  
• As were another 15 000 samples of bat viruses* - and a veritable zoo of caged passaging animals and/or virus samples from bats to macaques to mice to snakes to pangolin. (* Edit: In late 2021 a Laos bat became new closest match at 96.7% - WIV/EcoHealth - through PREDICT - collected samples from Laos over several years)
  
• WIV/EcoHealth scientists declared that some of the viruses collected were infectious to humans.
  
• WIV/EcoHealth passaged candidate viruses through animals and engineered/recombined viruses through Gain-of-Function experiments to make them more contagious.
  
• WIV/EcoAlliance’s handling of bats without PPE, according to photos below (courtesy https://twitter.com/BillyBostickson), looks bloody dangerous.
  
• Lab accidents happen - a lot.  SARS-1 has escaped six times.  Covid wouldn't even be the first pandemic caused by scientists.  This 2010 paper concludes that the origin of the H1N1 pandemic was a lab in China due to an accidental release of a frozen laboratory strain into the general population in 1971.
  
• Bio-security at the BSL-4 WIV was lax - it was worse at BSL-2 labs.  Even the Global Times reported the discharge of laboratory materials into the sewer after experiments without a specific biological disposal mechanism and chronic loopholes at laboratories.
  
• US intelligence reports saying, researchers at the lab fell ill in the fall of 2019 with symptoms consistent with COVID-19.
• Paper by Sorensen et al highlighting four crucial changes to the spike protein (making it infectious to humans). They note  that whereas this part of the virus is very stable in nature, these changes can be done simply in a lab. 

Edit: After this was written, the most damning piece of evidence of all came to light.  FOI emails obtained by Buzzfeed revealed that the scientists who wrote the notorious Proximal Origin paper published by Nature (aka The Pangolin Paper), all thought Covid looks engineered.  They admitted the paper was purpose-written to cover-up this probable origin scenario.
