Spy in the Sky

Today's Grauniad reported that the cops were using an automated drone to spy on crowds at the V Festival. According to the report, the drone is almost inaudible above 30m, and so small as to be practically invisible. So there's just no getting away from the all-seeing eye of the law, it seems. How long before the cops suggest building surveillance into new buildings, Big Brother style, on the grounds that if you've nowt to hide, you've nowt to fear? Not long, I expect.

Another little wrinkle of this drone is that it can spray a fine mist containing marker DNA, which invisibly marks 'suspects' so that they can be picked up and identified later. Talk about being pissed on from a great height...
