Oh the camaraderie, the flag-waving and all that special olympic spirit is starting to build up.
The BBC, who will of course be the preferred jingoistic broadcaster for the event, had this to say…
The American-made Long Range Acoustic Device (LRAD) can be used to send verbal warnings over a long distance or emit a beam of pain-inducing tones.
The equipment was spotted fixed to a landing craft on the Thames at Westminster this week.
Royal Marines operating in patrol craft from HMS Ocean are also heavily armed with conventional firearms.
In an article that contains no criticism of the measure or dissenting voices whatsoever, the BBC goes on to do its bit for US arms sales too…
The piercing beam of sound emitted by the device is highly directional. Some versions of the LRAD are capable of producing deafening sound levels of 150 decibels at one metre.
But the device, which was used this week during Exercise Olympic Guardian, can also be used to broadcast verbal warnings, such as ordering crowds to disperse.
LRAD Corporation has previously sold the device to the US Army, which deployed them in Iraq for crowd control.
They have also been bought by the US Navy and Air Force as well as a number of police forces worldwide.
It gets worse if you read the article.
