The Unmanned Aerial Vehicle (UAV) industry is growing rapidly, and this is causing some concern about individuals using UAVs for illicit purposes. The Cipher Brief spoke to Rachel Stohl, of the Stimson Center, about these concerns and the overall development of both UAV and anti-UAV technology. She says that both industries will continue to grow and innovate, but that they may move outside the U.S. if the regulatory environment does not improve.
