Two more mishaps have emerged in the nation's efforts to ensure the safety of travelers, and both emanate from Colorado. Officials at Denver International Airport concede that hundreds of bags were loaded onto jetliners in late December without being run through security scanners (via The Associated Press ). The breach has spawned a U.S. Transportation Security Administration investigation into what appears to be unintentional human error. In the second incident, Douglas Duchak, who worked at the TSA operations center in Colorado Springs for five years updating its computers with data from the Terrorist Screening Database and the U.S. Marshal's Service Warrant Information Network, is facing charges for attempting to sabotage the data, according to Reuters . He's facing 10 years in prison and a fine of $500,000 for attempted intentional damage to a protected computer. "We pleaded not guilty and look forward to putting our side of the story in front of a jury," says Duchak’s lawyer, M. David Lindsey (via the Colorado Springs Gazette ). Duchak was on the brink of being fired in late 2009. Documents say he wanted to damage the system that vets people who have access to sensitive information and secure areas within the nation’s transportation network.
