A former CIA software engineer has been sentenced to 40 years in prison for what the government called the biggest theft of classified information in CIA history and for possession of child sexual abuse images and videos.
To prove the charges. There have been enough cases of "she looks too young to be 18" where they were, in fact, 18. This database (which I thought was actually run by the FBI, but whatever) let's them show that the images were of Jane Roe, born May 5 1996, and the images/material were produced between 2008-2010.
IOW, to provide proof beyond a reasonable doubt that they were underage.
