TSA began deploying the SPOT program in fiscal year 2007--and has since spent about $900 million--to identify persons who may pose a risk to aviation security through the observation of behavioral indicators. In May 2010, GAO concluded, among other things, that TSA deployed SPOT without validating its scientific basis and SPOT lacked performance measures. GAO was asked to update its assessment. This report addresses the extent to which (1) available evidence supports the use of behavioral indicators to identify aviation security threats and (2) TSA has the data necessary to assess the SPOT program's effectiveness. GAO analyzed fiscal year 2011 and 2012 SPOT program data. GAO visited four SPOT airports, chosen on the basis of size, among other things, and interviewed TSA officials and a nonprobability sample of 25 randomly selected BDOs. These results are not generalizable, but provided insights. |
