At their recent meeting in Palm Springs, Barack Obama and Xi Jinping, leaders of the world’s two largest police states, exchanged jocular remarks about keeping citizens in line when they complain about massive surveillance procedures. “Like unruly teenagers,” said Xi Jinping. “Sometimes they just have to be grounded,” said Obama, to which Xi Jinping replied, “Drone ground them fast!” The two leaders chuckled and then walked off out of the hearing of reporters and photographers.
