The people in this picture are breaking the law. They aren't supposed to sit on that particular wall and there is a big fine for sitting there. I cannot imagine why this law exists. What possible harm in having them sit on that wall?
          The wall faces the sidewalk and they are maybe too visible to passing people. The cops that enforce this bit of idiocy are simply doing their job: acting on the unspoken but clear desire of the liberal folks of Madison to make The Family disappear.
