A cheap $300 drone anyone may purchase, but still a drone. It was shot down anonymously, by small arms fire, here in the USA.
For Krauthammer's remarks, see here. For the drone shoot-down, which was in February already, see here.
What Krauthammer doesn't realize is these things are going to get so small you'll never know one from the moth resting on the side of the house in a shady cool spot in the heat of the day.
Better shoot while the shootin's good, because pretty soon you're going to need a flyswatter instead of a shotgun.
