Using the B aB ar measurements of the Dalitz plots for B^0 → K^+π^0π^-, B^0 → K^0π^+π^-, B^+ → K^+π^+π^-, B^0 → K^+ K^0 K^-, and B^0 → K^0 K^0 K̅^0 decays, we demonstrate that it is possible to cleanly extract the weak phase γ. We find four possible solutions. Three of these -- 32^∘, 259^∘, and 315^∘ -- are in disagreement with the SM, while one -- 77^∘ -- is consistent with the SM. An advantage of this Dalitz-plot method is that one can obtain many independent measurements of γ, thereby
