Haven't you seen the old movie "Airplane!" from around 1980? Women passengers on their way to the airport gates walk past a security and a camera. From this angle you can see the male guard watching the monitor -- which shows the woman with no clothes on! Or Total Recall from 1990 (protraying the world nearly a century in the future), anyone entering the subway rail system freely walks past a large X-ray scanner screen, with security observing skeletons walking through. Attempting to bring a gun results in an immediate alarm. Of course, the guy from "A Fish Called Wanda" easily makes it through airport security with a gun..
