Early on Monday morning, the Secret Service found a drone on the White House grounds. A White House spokesperson said it poses no threat. But it does—at least to the way we think about "drones."Ordinarily, the White House is the launcher of drones, not a target of them. The executive branch has been criticized for using Predator drones to launch airstrikes that have left more than 2,400 dead—more than 10% of those reportedly civilians.So it seems just a little cavalier to say this new drone posed no threat to President Obama, his family or the White House staff.
