Response to Horton and Dewdney
  There are some points in the reply of Horton et al. [http://stacks.iop.org/JPhysA/35/7963] to my comment [quant-ph/0202140] on their paper [quant-ph/0103114] which I cannot let stand without a response. I provide here some clarification of how much I proved about the set of points where their law of motion is ill-defined.
