Equal Counts in Two Groups

Two named groups — such as two rows or two columns — contain exactly the same number of Suspects (or Innocents). The constraint equates their counts but says nothing about what that shared count is. Resolve one group first using other clues, and the second group's count becomes known for free. Note that the two groups may overlap (e.g., a row and a column share one cell); if so, the shared cell counts toward both sides of the equation simultaneously.
