I said the negative effects of a death due to crime or terrorism is greater than that of a death due to disease.

Look at e.g. Chicago. 500 or so murders a year, dwarfed by the number of deaths from heart disease, etc, and people freak out. But that reaction has an economic cost--it's harder to get middle class people to move into and stay in the city when they fear crime.

Maybe people shouldn't be so unnerved by crime and terrorism, but they are. 1,000 traffic deaths a year in Illinois does absolutely nothing to curb car culture. 1,000 terrorism deaths a year in Illinois would gut the economy of the state as people fled to saver environs.
