The problem of crowd control

Ultimately the aims of contemporary architecture and the police converge most strikingly around the problem of crowd control. As we have seen, the designers of malls and pseudo-public space attack the crowd by homogenizing it. They set up architectural and semiotic barriers to filter out 'undesirables'. They enclose the mass that remains, directing its circulation with behaviorist ferocity. It is lured by visual stimuli of all kinds, dulled by musak, sometimes even scented by invisible aromatizers. This Skinnerian orchestration, if well conducted, produces a veritable commercial symphony of swarming, consuming monads moving from one cashpoint to another.
