From one of my favourite blogs, History is made at night –
A black box emitting a high pitched pulsing sound designed to deter loitering teenagers is being used in thousands of sites around Britain just a year after its launch, prompting warnings from civil liberties campaigners that it is a “sonic weapon” that could be illegal. The Mosquito device, whose high-frequency shriek is audible only to those under around 25, has been bought by police, local councils, shops, and even private home owners, to tackle concerns over groups of young people congregating and causing disruption.
Apparently from the Guardian initially.
Crazy stuff. I wonder how long it will be before they are widely deployed in shopping malls.
Even more crazy is that this is from the SAME company that developed the ‘secret teen-only mobile phone ringtone’ – the mosquito ringtone?
