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