Well, they got permission first.

A group of researchers led by Professor Todd Humphreys from the University of Texas at Austin Radionavigation Laboratory recently succeeded in raising the eyebrows of the US government. With just around $1,000 in parts, Humphreys’ team took control of an unmanned aerial vehicle operated by the US Department of Homeland Security.
After being challenged by his lab, the DHS dared Humphreys’ crew to hack into their drone and take command. Much to their chagrin, they did exactly that.
Humphrey tells Fox News that for a few hundreds dollar his team was able to “spoof” the GPS system on board the DHS drone, a technique that involves mimicking the actual signals sent to the global positioning device and then eventually tricking the target into following a new set of commands.
The real danger here, Humphreys added, is that the US plans to have several thousand drones operating stateside in the coming years. A terrorist could easily and cheaply hack one of these and then control it, 9-11 style, as a kamikaze missile:
“In five or ten years you have 30,000 drones in the airspace,” he tells Fox News. “Each one of these could be a potential missile used against us.” . . .
“What if you could take down one of these drones delivering FedEx packages and use that as your missile?” Humphreys asks. “That’s the same mentality the 9-11 attackers had.”
