The following happened to Doctor Li Wenliang:
> On 3 January 2020, police from the Wuhan Public Security Bureau investigating the case interrogated Li, issued a formal written warning and censuring him for "publishing untrue statements about seven confirmed SARS cases at the Huanan Seafood Market." He was made to sign a letter of admonition promising not to do it again. The police warned him that any recalcitrant behavior would result in a prosecution.
Being detained and forced to sign a letter on threat of prosecution is the practical equivalent of being arrested.
> If there was foreknowledge of a lab leak, these doctors would be under surveillance and stashed away in safe house away from family/friends/work for months/years like in other politically sensitive cases.
There is no evidence that doctors like Doctor Li Wenliang had knowledge of the origin, and were targeted for reporting on the virus.
Huang Yan Ling was a researcher at the virology lab in Wuhan that has been missing since right before the outbreak.
Huang Yan Ling stopped working at WIV in 2015. The only reason she's noteworthy is conspiracy theorist tried to link her as patient 0. People have some expectation that PRC should indulge in random conspiracy theory by parading her around. Like is US going open up fort Detrick for scrutiny? No because entertaining the whims of yahoos is ridiculous.
