Project Summary: Indicators and Warnings Searching for and recognizing indicators of potential terrorist activity require a great deal of focus, determination, and patience, especially given the extensive amount of information that must be reviewed. At best, indicators can prevent terrorist attacks. At worst, indicators can be inaccurate or irrelevant. Indicators of potential terrorist activity are wide-ranging and may include exhibiting violence against persons or property, purchasing high-performance automatic weapons, and displaying civil disobedience (Global Security, 2009). Warnings are notifications sent to government officials and/or the public about potentially imminent terrorist threats. Undoubtedly, warnings can save lives. However, if warnings are based on inaccurate or irrelevant information they also can heighten security and create fear without reason.
