We actually have at least two different investigation committees lead by lawyers and scientists. Including Wolfang Wodarg, who successfully and officially debunked the swine-flu pandemic as fraud. He revealed very clearly how the pharma industrie forced contries into contracts to buy vaccines and how the WHO suddenly changed the criteria for pandemics and so on and so on.

Of course that doesn't mean that you can simply conclude that corona is also a fraud. But I can definitely understand all the conspiracy theorists going crazy. :D
