At 14 min Robert Kraft randomly placed a black pin in the cemetery map plot of W ISHAM and removed the white pin. At 21 min Kraft stated he took a white pin out "quite at random" and put a black pin in its place. Reverse of what he actually did.
At 14 min Robert Kraft tests a theory that he can cause a death by placing a black pin in the cemetery plot map and removing the white pin. To make the selection he looks away so as to make it appear to be random. At 15 min the camera zooms in on the map to reveal about 9 pin holes in the selected plot, W ISHAM. Obviously, random selection requires practice.
