The heartbreak would come when there are simply too many American victims of Ebola (in Africa) for available transport or treatment facilities.
Triage is an ugly business.
Somebody with political clout would pull strings and cut some corners for their relatives. Safety protocols would get bypassed entirely and there would be an accident in transport.
That is most likely how Ebola may be introduced to the American public.
We are a long way from death dealing triage of Americans in Africa.
You already have us letting Americans die and are already creating your conspiracy theories on how the rich and powerful introduce Ebola to America through bribery.
Try to get a grip on yourself and your imagination.
