As someone who has a whole shed load of neurological problems, including pretty much all the ones those embassy people have and there was no evidence of abnormality on my MRI or EEGs can we assume that I've been attacked by an ultra-sound weapon too?
Full disclosure: I am not an undercover CIA operative.
Also, has anyone ruled out mass-hysteria? I know that sounds daft but it's happened before (e.g. a San Diego Navy barracks in the 80s) and there is a long history of groups of people spontaneously developing random neurological symptoms, the cause of which is never discovered...
