Virus source

Early last year when the Covid first appeared in Wuhan, China some suspected that it came from a nearby lab where research on Covid like viruses was taking place. According to US experts the lab was not designed with proper safety protocols and had a history of problems regarding safe procedures. When some suggested that the virus may have come from this lab they were dismissed as conspiracy theorist. The better explanation was that it came from animals called pangolins that were sold at a wet market. Would the logic of the situation indicate that the lab was the more likely source and if so why wasn't the lab considered the prime suspect. There is now an investigation under way which is a way to kick the can down the road until everyone forgets about the whole thing until the next virus hits.
