Before, After, During: Michael Chertoffs Post-Katrina Arguments

Days before Hurricane Katrina struck New Orleans, Michael Chertoff surprised doctors from coast to coast by declaring himself the principal managerial decision-maker in all national public health crises in the United States. Unfortunately for Chertoff, the public health community has been busy reinventing its orientation to data, and his statements during the hurricane relief and cleanup flew in the face of its newly overhauled standards of evidence and reasoning. This essay explores the time orientation in Chertoff's arguments in defense of FEMA and the Department of Homeland Security's response to Katrina, and describes the mismatch between his assumptions and those derived from the epidemiological turn in disaster management.
