Terrorist and criminal watch list systems -- sometimes referred to as watchout, lookout, target, or tip-off systems -- are important tools in controlling and protecting our nation's borders. The events of 9/11, and other incidents since then, have highlighted the need to share these watch lists. In light of the importance of border security, this report identifies Fed. databases and systems that contain watch lists, the agencies that maintain and use them in protecting our nation's borders, the kind of data they contain, whether Fed. agencies are sharing info. from these lists with each other and with state and local governments and private org's., the structural characteristics of those lists that are automated, and whether opportunities exist to consolidate these watch lists.
