An NBC News report in December 2005 revealed that the military maintained the database of "suspicious incidents," including peaceful anti-war protests and groups. Vietnam war era regulations limit what information the military can collect about people and activities taking place inside the US, and the Pentagon launched an investigation into possible misuse of the program. According to DOD officials, the investigation revealed that 261 entries were improper and subject to removal. Military officials have also acknowledged that some records were kept longer than the DOD's internal 90-day policy even though the groups had been deemed not to be a threat. US Sen. Patrick Leahy (D-VT) welcomed the decision Wednesday, saying that " Talon was another costly, controversial and poorly focused venture that did not make us any safer, while taking a hefty toll in Americans' privacy and Americans' tax dollars. Without clear rules and close oversight, databases like this can easily be abused to violate the public’s constitutional and privacy rights."
