In a startling plea for official censorship, Amy E. Smithson of the Henry L. Stimson Center has urged the government to "close down" web sites run by environmental organizations if they publish information about hazardous materials in local communities around the country, claiming that such information could be used by terrorists. "In this day and age, Washington can no longer afford to hand any interested individual a road map to the chemical calamities they could cause with the toxic materials located in communities nationwide," Smithson testified at a House Transportation subcommittee hearing on "Right to Know After September 11th."
