The General Accounting Office (GAO) issues a report examining problems affecting the performance of security screening staff at US airports. It warns: “The threat of attacks on aircraft by terrorists or others remains a persistent and growing concern for the United States. According to the Federal Bureau of Investigation, the trend in terrorism against US targets is toward large-scale incidents designed for maximum destruction, terror, and media impact.” Though the GAO describes the performance of screeners in detecting dangerous objects like handguns as “unsatisfactory,” it makes no recommendations to revise current screening practices.
