The sign of A CP(K – π +) < 0, the evidence for , and the possibly sizable A π π and S π π in all suggest that final state rescattering may be needed in decay, which is echoed by large color suppressed modes. An SU(3) formalism of rescattering in PP final states leads to interesting predictions, in particular allowing for small .
