The First, Fourth, and Fifth Amendments to the Constitution are often retracted, if temporarily, in the name of national security. Supporters of this logic reason that in moments of national crisis, unity should be the tune of the day, and those who refuse to sing along—dissident citizens and others— are dangerous denizens who are jeopardizing national security. Suppressing the actions of these people is thus seen as more acceptable by the general public. State suppression is rationalized rhetorically in ways that emphasize exceptional, perilous circumstances.
