Audit finds major gaps in U.S. bio weapons detection system By Associated Press Share: FILE - In this Nov. 12, 2003, file photo, an area of the Brentwood postal facility in Washington, is still closed during a media tour. The region's main mail processing center is almost ready to reopen for the first time in two years, after undergoing a $130 million-dollar Anthrax decontamination and renovation. An audit has found gaps in a program intended to provide the U.S. with an early detection system of a biological weapon attack. The U.S. created BioWatch in 2003 in response to the mailing of anthrax-laced envelopes to news media and government offices two years earlier. (AP Photo/Manuel Balce Ceneta, File)
