Gary Ackerman provides a clear-headed assessment of Chemical, Biological, Radiological and Nuclear (CBRN) Terrorism. In an age of mass casualty terrorism, the use of CBRN weapons by terrorists poses sobering questions which can be easily inflamed and inflated in public imaginations. Ackerman, however, provides a sensible and informed assessment of the threat and challenges here.
