Interestingly Yugoslavia was one of the very few countries of the world that did not appear as a customer on the list of 110 countries. Every tin-pot dictatorship in Latin America, Africa, the Middle East and Europe was on the list, along with most of the more 'respectable' nations, including Australia. So much for humanitarian principles. US companies freely advertise thumbcuffs, thumbscrews, leg irons and shackles, whips, electroshock devices, suspension equipment, immobilisation guns, shock batons and even 'specially designed implements of torture'. And as noted, they don't care where they go.
Business is business.
But that's old fashioned stuff. Research in torture technology and crowd control is booming in US nuclear laboratories such as Oak Ridge, Lawrence Livermore and Los Alamos. Thanks to their research, the world's police forces already have available for 'crowd control' such devices as ultra-sound generators which cause disorientation, vomiting, involuntary defecation, and disturbance of the ear thus causing loss of balance. Apparently the system which uses two speakers can target individuals in a crowd. Handy to nab the ring-leaders.
