  "abstract": "We study a relation between the weak phase $\\gamma$ and the rates and CP asymmetries of several $K \\pi$ decays of $B^+$, $B^0$, and $B_s$, emphasizing the impact of the latter measurements. Current data indicate large SU(3) breaking in the strong phases or failure of factorization (including its application to penguin amplitudes) in $K \\pi$ modes of $B^0$ and $B_s$. SU(3) and factorization only remain approximately valid if the branching ratio for $B_s \\to K^- \\pi^+$ exceeds its current value of $(5.27 \\pm 1.17) \\times 10^{-6}$ by at least 42%, or if a parameter $\\xi$ describing ratios of form factors and decay constants is shifted from its nominal value by more than twice its estimated error.",
