In another sign of the times, the Justice Department appointed its first federal prosecutor in charge of export control enforcement. Stepping into this job is Steven W. Pelak, a U.S. attorney, who will be responsible for investigating illegal exports of U.S. arms and sensitive technology. Pelak hosted a national export control conference earlier this year where federal prosecutors received detailed instruction and guidance. In recent years, the Justice Department has prosecuted arms suppliers for illegally selling missile technology, military night vision data, fighter jet components and combat helicopter data to foreign nations.
