Computer profiles generate objects for surveillance - they instruct or train the observer in what to watch and how to watch for it. Police, psychiatrists, educators, physicians, to name just a few groups, increasingly use profile technology for early or pre-identification of various traits within preselected populations - if you match enough elements of the profile, you could become atarget, even before any trait has manifested itself. To prepare the observer, to train the observer to see, and in the last instance, to be the observer's eyes, this is the imaginary of the simulation of surveillance.
