It was a spec­tac­u­lar event in terms of media impact and mas­sive scale of urban ter­ror­ism. An event that was sym­bol­ic of a whole new sort of mode of polit­i­cal vio­lence against the cen­ters of the glob­al economy—the so-called world cities, the world cen­ters of finan­cial, eco­nom­ic, and mil­i­tary pow­er. And an attack orches­trat­ed through means of elec­tron­ic finance, through appro­pri­at­ing the infra­struc­tures of the city to tar­get the city. So I’m par­tic­u­lar­ly inter­est­ed in how it’s an event that has been used to under­line the vul­ner­a­bil­i­ties of con­tem­po­rary urban life.
