Disabling Terrorist Technology

Brilliant! If terrorists are in the country, let's shut off GPS so that they get lost. Of course, I hope someone pointed out to our president that while potentially causing millions of dollars in potential revenue loss and associated costs (bringing the system down, bringing it up, repairing the parts that didn't get brought up or down correctly) can all be foiled by a two dollar map, just as the initial terrorist caused billions of dollars in damages with a couple of box cutters from Home Depot. If I was a terrorist, I wouldn't even try to leave the country right away, leaving and showing up in a new place too shortly after the attack would arouse too much suspicion. Getting away from the scene of the crime would be fairly easy with the ensuing chaos.
