"There is something uncomfortable – perhaps even sordid – about covert surveillance, which is not necessarily expiated simply because a particular operation is instrumentally effective. The feeling seems at least in part to be connected with the loss of privacy suffered by targets of surveillance, and by those with whom they associate. Discomfit is further compounded by the worry that the informational fruits of surveillance could be misinterpreted (the camera never lies?), misappropriated or otherwise abused."
