  I discuss the effect of final state interactions on the determination of the
CKM angle \gamma from B -> K + pi decays. Using a simple Regge-based model for
rescattering processes, I argue that such effects could be substantial enough
to make it problematic to obtain reliable limits on \gamma in this way.
Fortunately, an analysis of B -> K + K decays may provide model-independent
bounds on rescattering contributions.
