Look at what happened during 9-11, all area emergency personnel were sent to the World Trade Center and many of them were killed. I doubt if many were available to respond to other emergencies around NYC and even if they were, look at the gridlock. In a major emergency, you can't count on police or emt or fire response for that matter. You will have whatever training and or supplies that are available to you and you may be totally on your own for several days or weeks. People are woefully unprepared in this country and rush out at the last minute for hurricane supplies or storm supplies, etc. It is up to you, but you can't count on the government, local state or federal to protect you or come to your rescure.
