Update: Dec. 27
The New York Times today has a story (by Denise Grady and Donald G. McNeil, Jr.) on the debate over the experiments having even been done, let alone the idea of publication, because the virus will inevitably "get out". What makes this virus more dangerous is that it is transmissible person-to-person as well as bird-to-person. It says possession of the virus needs to be restricted so that at least it cannot get out as "soon".
