Furthermore, the WHO's own team admitted recently that they were simply not equipped to do any kind of forensic investigation of the lab (https://www.nationalreview.com/corner/world-health-organizat...):
> [Dominic Dwyer, a medical virologist at New South Wales Health Pathology in Sydney, Australia, and a member of the WHO team] says that the team didn’t see anything during its visits to suggest a lab accident. “Now, whether we were shown everything? You can never know. The group wasn’t designed to go and do a forensic examination of lab practice.”
Even if they were appropriately equipped for such an investigation, what's the use when China had blocked their visits until a year later, when they've had ample time to cover any evidence. The whole situation is highly suspicious, from the initial suppression of news reports of the virus, to delaying international lab visits, to the deletion of studies from that Wuhan lab (https://www.thesun.co.uk/news/13701168/covid-cover-up-china-...).
