As I'm sure many have already surmised, this is nothing more than a massive waste of time to provide the more ignorant of the citizenry with a bubble-thin illusion of security. And the really sad part is that anyone with an iota of know-how can get data into or out of the country relatively easily. Does no one at DHS think that the bad guys would stay informed of laws like this? Are they going to start opening all packages coming into the U.S. as well, under the guise of "protecting" us from the terrorists?
My best friend works for a large company as a software engineer. He is contracted out to a defense contractor at the moment, working on a highly classified project. And his work has provided him with a laptop. Do they get to sieze that as well, ITAR clearances notwithstanding?
