On April 28, 2004, the United Nations Security Council, acting under Chapter VII of the UN Charter, unanimously passed UNSC 1540. The resolution "decided that all States shall refrain from providing any form of support to non-state actors" attempting to obtain or use weapons of mass destruction, "adopt and enforce appropriate effective laws" to that effect, and "take and enforce effective measures to "prevent the proliferation of" WMD. To carry out its part of this mandate, the UNSC established and renewed a Committee, which has mainly and usefully assisted States in adopting "appropriate effective laws." This study, in collaboration with Committee members, has focused on implementation mechanisms and indicators of performance in border and exports controls, securing materiel and facilities, and adapting controls to State needs. We conclude that the most meaningful measures of implementation need to be more broadly adopted and that the 1540 Committee needs a more extensive staff in order to extend its role to disseminate States' experience with those measures. We also conclude that mechanisms need to be developed to facilitate information sharing between the Committee and the private sector.

A major component of the strategy to prevent attacks with Weapons of Mass Destruction (WMD) by transnational terrorist groups requires the widespread utilization of chemical, biological and radiological detection systems. Whether or not one can actually deploy these sensors may well depend on the public perception of the sensor's invasion of their privacy and the court's interpretation of the sensors' challenge to the Constitution's search and seizure protections. However, if scientists and engineers designing new sensors take cognizance of the perspective taken by courts in the past, they will stand a much better chance of providing technical solutions that will balance the Fourth Amendment and civil liberties against the modern realities of terrorist threats. This seminar will discuss and solicit ideas on how legal interpretations of the fourth Amendment can be used to help design modern sensor systems.

Don Prosnitz is currently the deputy drector (programs) for nonproliferation, homeland and international security at Lawrence Livermore National Laboratory and is responsible for overseeing all of the directorate's technical programs. He received his BS from Yale University and his PhD in physics from the Massachusetts Institute of Technology. He then spent two years as an assistant professor in the Engineering and Applied Science Department at Yale before joining Lawrence Livermore National Laboratory as an experimental laser physicist. Over the next three decades, he conducted research on lasers, particle accelerators, high-power microwaves, free-electron lasers, and remote sensing, and managed the design, construction, and operation of numerous research facilities. In 1990, he was awarded the U.S. Particle Accelerator Award for Achievement in Accelerator Physics and Technology; in 2002, he was named a Fellow of the American Physical Society. He has served on multiple technical panels, including a Defense Science Board study and various intelligence committees. He is currently a member of the National Academies of Science Board on Chemical Sciences and Technology. In 1996, Prosnitz was briefly detailed to the Department of Energy where he provided technical support to the Office of Nonproliferation and National Security. In 1999, Prosnitz was named the chief science and technology advisor for the Department of Justice (DOJ) by Attorney General Janet Reno. In this newly created position, he was responsible for coordinating technology policy among the DOJ's component agencies and with state and local law enforcement entities on science and technology projects and programs. He served on numerous interagency working groups and federal committees, including the National Science and Technology Council, the Data Management Improvement Act Task Force (immigration systems), and the National Human Research Protections Advisory Committee. He advised the attorney general and DOJ officials and component agencies, such as the FBI, DEA, and former INS (Immigration and Nationalization Service), on such technical matters as weapons of mass destruction, forensics, human subject protection, immunization policy, immigration policy, biometrics, border protection, and information technology. In 2003 he returned to LLNL where he promotes continuing education of the workforce with a special emphasis on the interaction of society and technology.

Plutonium (Pu) and highly enriched uranium (HEU), the fissile material that is the sine qua non of nuclear weapons, manifest fingerprints that are unique to the manufacturing processes employed in their creation. Such fingerprints are not as clear as those made famous by the FBI for decades, or as DNA is today, but they are fingerprints, nonetheless. The technical challenge is to develop the processes that will link, beyond reasonable doubt, the fissile material to its manufacturer. If the technical challenges can be met, political challenges lay beyond and must be resolved before the civilized world can be assured that the fissile material that generates a nuclear explosion can be traced to its source, but if it can, many benefits to society will result. Among these are deterrence of potential suppliers, credible delay in reacting to nuclear terrorism, and international cooperation of the highest sort.
