Nearly 10 years after the September 2001 terror attacks, the U.S. government has significantly improved homeland security but still lacks a system to know who is leaving the country and exactly what is inside luggage checked at airports, according to a GAO report.
The report from GAO concluded that, since the Homeland Security Department was organized in 2003, it completed about half the nearly 1,500 recommendations made by federal auditors. But there are still gaps, said the report, including the lack of a biometric exist system and enhanced explosive detection technology for checked baggage at airports.
