His actions are a pretty strong indication that he knew he had been exposed and jumped onto a plane to get to America where he had the best chance to stay alive. He made a mistake, which is understandable in the circumstance, when he did not tell the ER personnel that he was from Liberia and had been closely exposed to Ebola. I understand his actions entirely . I fault the USA government for not closing the Liberian airports as soon as Ebola was known.
He DID tell the ER nurse that info, but it was ignored.
Not our call. The guy flew in from Brussels. The problem is that he had a visa and there are 13,500 more visas in the hands of people like him.
