Exactly One Person Has N Suspect Neighbors

Among all cells in the named group, exactly one cell has exactly N Suspects (or Innocents) in its 8-neighborhood. All other cells in the group must have a neighbor count different from N. Neighbors are counted globally across the whole grid, not only within the group. This requires testing each candidate cell: which one can have exactly N Suspect neighbors while every other group member simultaneously has a different count? The constraint is violated as soon as two cells in the group both achieve a neighbor count of N.
