You read about all these terrorists--most of them came here legally, but they hung around on their expired visitor visas, some for as long as 10-15 years, unable to be found so they can be deported. The current system doesn't have the slightest idea where most of them are.
Now, compare that to Blockbuster: They know your name, address, phone number, workplace address, and who knows what else about you. If you're a day late with a video, those people are all over you.
Now that Blockbuster is going out of the video rental business, let's put them in charge of Immigrant Tracking. It shouldn’t take them more than a couple of weeks to find all the illegals. Maybe, in the course of tracking down all these foreign intruders, Blockbuster might even find some of their old videos that were never returned.
