For years, the United States has used drones to track foreign terrorists overseas and catch outlaws along the border. But now, thousands of drones are heading to the homeland. Drones are already used for certain purposes here in the United States, but the FAA will soon dramatically expand the use of drones to operate nationwide by the year 2015. It is estimated, by 2020, 30,000 of them will be flying in American skies. Who and what will all of these new eyes in the sky be looking at? No one really knows. But whether we like it or not, the drones are coming.
