  We consider the strong rescattering effects that can occur in the decays such
as B -> K pi, K* pi, K rho... and their impact on direct CP violation in these
modes. First we discuss, in general, how the CPT theorem constrains the
resulting pattern of partial rate asymmetries leading to different brands of
direct CP. Traditional discussions have centered around the absorptive part of
the penguin graph which has Delta I=0 in b -> s transitions and as a result
causes ``simple'' CP violation; long-distance final state rescattering effects,
in general, will lead to a different pattern of CP: ``compound'' CP violation.
Predictions of simple CP are quite distinct from that of compound CP. Final
states rescattering phases in B decays are unlikely to be small possibly
causing large compound CP violating partial rate asymmetries in these modes.
CPT theorem requires a cancellation of PRA due to compound CP amongst the
$K\pi$ states themselves; thus there can be no net cancellation with other
states such as K*\pi, K\rho etc. Therefore, each class of such modes, namely K
pi, K rho, K^*pi, K a_1 etc. can have large direct CP emanating from
rescattering effects. Various repercussions for the angle $\gamma$ are also
discussed.
