They're called NAVs, Nano Air Vehicles, and despite the appearance of such sound & vision surveillance vehicles still being lab-based only, they've already been field-tested in America's war zones, and in the homeland. The newer models won't be quite so noisy, or so obvious :



Presumably, adding lethal and/or non-lethal weapons to NAVs is only a matter of time.

The plan is for 'nano' spy vehicles to become as omnipresent as CCTV in the UK in the next decade, and not just the UK, but the US, Australia, most of Europe, Japan, China, eventually most of the world.

Curiously, the near total failure of CCTV to live up to its original 'We Must Have These' promise as a major crime fighting tool is being used as a pitch for the UK government to buy hundreds, if not thousands, of NAVs.

If advertising companies load NAVs with sales pitches and theme music and fly them into peoples' faces, it should be legal to catch them and smash them to pieces.
