Our military has some nasty stuff you have never heard of. While it seems to be humanitarian in bringing Ebola patients to our soil for care, the risk to an entire Nation if an accident were to occur could wipe out millions. Atlanta is populated by close to 1/2 million people. That is no small village in Africa. With Air travel all you need is one infected person to start sending the virus all over the world.
While some may think accidents do not happen, Mr. Murphy is always willing to throw a wrench into the operation. The fact that these two people contracted Ebola proves accidents happen. You can only be so careful, and mistakes happen.
