Spy Drones take to the sky in the UK

Novotny writes: The Guardian and various other sources are reporting that 'the UK's first police "spy drone" has taken to the skies'. Originally usd in military applications, these drones are being put into use as a senior police officer warns the surveillance society in the UK is eroding civil liberties. In the UK, there are an estimated 4.2 million surveillance cameras already, and you are on average photographed 300 times a day going about your business. Is there any evidence to suggest that this increasingly Orwellian society is actually any safer?
