TSA loses harddrive with important data

It was reported by the Washington Times that the TSA (Transportation Security Administration) is missing an important disk drive containing data of over 100,000 employees. These data are considered highly sensitive since they "include the archived records of employees and their Social Security numbers, dates of birth, financial allotments and payroll information."

Good job guys! I keep hearing about misplaced laptops and data disks. In most of these cases, the missing items were all considered to be important due to the information they contain. How do you lose something that is considered a risk to national security? Seriously, did someone go to the john and forget to bring it out with him? What happened to having the items handcuffed to the carrier? At lease he would notice when the briefcase go missing.
