crowd control

How do you keep people away from a site without direct physical confrontation, when someone is almost sure to get hurt? Tear gas has variable effects and depends on wind; rubber bullets have killed. But what about a system that inflicts pain at a distance, without contact?

Three-metre high security fences, heart-stopping tasers, a bone-smashing water cannon, mobile prison buses and — perhaps most disturbing of all — the threat of automatic incarceration for randomly abducted protesters? Welcome to the growing international phenomenon of “population control”. The Asia Pacific Economic Cooperation (APEC) forum is in Sydney, and NSW security chiefs are telling you to follow orders, shut up and stay away. Prison cells are ready and waiting if you fail to heed the warning.
