How long before the US government forces package delivery companies to spy on Americans?

Republican presidential candidate Newt Gingrich rallied support from a crowd of about a hundred at Stephens Convention Center in Rosemont Wednesday afternoon, following losses in the Alabama and Mississippi primaries on Tuesday.

Gingrich told the crowd FedEx and UPS track 24 million packages a day, with no additional cost to customers.

“Now over here you have the federal government, the world that doesn’t work,” Gingrich said. “And the federal government today cannot find 11 million illegal immigrants even if they’re sitting still.

“So one of my suggestions was, what if we were to mail a package to every person who’s here illegally, and then when it got delivered we would pull them up and we would know exactly where it was because it would be in UPS and FedEx.”
