Abstract :
Developed, deployed, and sometimes demoted – The terrorist attacks of 11 September 2001 sparked a security mania in the United States that included a brassbound push for new surveillance technology– one that 10 years later has had mixed results. Radiation monitors for incoming cargo have been deployed en masse, but their utility remains dubious. Other technologies–such as the airline passenger imagers used by the Transportation Security Administration (TSA)–seem to work and have proliferated but leave some people feeling creeped out. Below, we compare five technologies pre-9/11 and today.
