According to this BBC article, "The Ministry of Defence has confirmed a sonic device will be deployed in London during the Olympics". Despite the device's ability to "emit a beam of pain-inducing tones," we're assured that it'll be more in "send verbal warnings over a long distance" mode. And although this "device" has been used "to repel Somali pirates" and in Iraq for "crowd control", we're to understand that it's certainly *not* a weapon. (It will, however, soon be in use in the United States as well.)
Why even bother with the doublespeak? As the roles of police and military continue to blur in the West, it's clear that the capacity to crush dissent grows increasingly as a priority. The Obama administration has, frighteningly, refused to dismantle the national security regime established by its predecessor. And just as stirring speeches embody a deft deployment of sound to the end of persuasion, this new weapon-- excuse me, device-- offers a new entry in the growing field of acoustic coercion.
