We present a simple isospin invariant parametrization for (B → Kπ) decay amplitudes which consistently includes CP violation and (quasi-elastic) hadronic final states interactions. We find that the observed (B → Kπ) decays do not lead to a significant bound on the angle γ of the unitarity triangle. On the other hand, we claim that a sizeable CP violation asymmetry in (B^±→ Kπ^±) rates is by no means excluded.
