Some of the best biotech and medical research personnel in the world are Paki, Iranian, Egyption etc. Why is it not possible that a couple of them put their training to use for Muslim Radical Terrorist? I do not believe in the odds it takes for 4 viruses to mutate and come together naturally, especially from such diverse places in the world, and land at a point of entry to the US that has as many going south as north. It just does make sense to me.
