Я очень благодарен за разъяснения. Проблема только в том, что они не имеют ничего общесго с действительностью. Так, городская легенда. Вот что говорит официальный документ DHS: In the event of a terrorist attack, natural disaster or other large-scale emergency, the Department of Homeland Security will assume primary responsibility on March 1st for ensuring that emergency response professionals are prepared for any situation. This will entail providing a coordinated, comprehensive federal response to any large-scale crisis and mounting a swift and effective recovery effort. The new Department will also prioritize the important issue of citizen preparedness. Educating America's families on how best to prepare their homes for a disaster and tips for citizens on how to respond in a crisis will be given special attention at DHS.
Так что вопрос об ответственности закрыт.
Update:
