One of the thing is that Western scientists takes the Wuhan lab's claims at face value, and builds their arguments based on Western standards. The BSL4 level has people claiming the lab is more like a dentist's office, which is troubling to hear.

Anyone following it for the past year would know there's too many photos of the Wuhan scientists handling the bats without gloves [1] and their hands covered with rashes from getting bitten by bats.

Also there's promotional videos [3][4] of the Wuhan scientists taking samples from an actual bat cave. Of course there would be transmission if things are done so shoddily.

Not to mention a Chinese researcher turned whistleblower wrote several papers on how the virus is manufactured in a lab setting. Obviously the bar to verify her claims is very high, as most people don't have the technical background to even read through her papers, but it shouldn't be that easily dismissed or brushed aside by experts [5][6]. An analogy is that even before arriving at the concentration camps, the Allies didn't know how horrible things were and had to video tape the liberation of the Jews as their conditions are just incomprehensible to people back at home.
