That is a good argument. They are certainly not acting innocent.
But lets say it is 50/50 whether they cooked it up in a lab. We may never know.
But if they deliberately loosed 5 million people on the world, that we can I think figure out, and that is just as bad.
We must have an investigation of the outbreak in Wuhan. The Chinese must grant the world total transparency. The truth must come out. If Chinese officials are innocent, they have nothing to hide. If they are guilty, they will refuse to cooperate.
The real concern here is whether the rest of the world has the courage to demand a real and thorough investigation. We need to be fearless in this demand and not allow economic interests to play a coy and dishonest game of denial. We need an honest inquiry. We need it now.
