DHS is the poster child for mission creep. The White House suggested last year that they could help track down "circumvention devices" such as game console mod chips. From the Office of White House's "Copyright Czar":
“[It] is illegal to import or traffic in devices that can be used to circumvent technological measures that control access to copyrighted works,” they wrote. “When DHS discovers the importation of a potential circumvention device, current law does not authorize DHS to share a sample with a rightholder to aid CBP in determining whether it is, in fact, a circumvention device. Allowing DHS to provide a sample would aid enforcement efforts.”
