  An analysis of $B \to K\pi$ decays is given, assuming a small elastic $\pi K
$ rescattering phase difference.Using factorization model only for the
tree-level and electroweak penguin amplitudes, we show that the strong penguin
amplitude, its absorptive part and the CP-violation weak phase $\gamma$ can be
obtained from the measured $B \to K\pi$ branching ratios. The strength of the
strong penguin and its absorptive part thus obtained from the CLEO data, are
found to be very close to factorization model values and suggests a current $s$
quark mass around $m_{s} = 106 \rm MeV$. The central value of $\gamma$ is found
to be around $76.10^{\circ}$, with a possible value in the range
$50^{\circ}-100^{\circ}$.
