The data the TSA is using and the ancillary information linked to the requested field data does not account for unreported/underreported identity theft and the risk that poses. Furthermore, background checks by various government agencies don't amount to much of substance most of the time; lots of miscreants go about for years without attracting attention. Not only is this a waste of time, money and resources, it's also not effective (amongst other flaws).
