It is shown that inclusion of charming penguins of the size suggested by
short-distance dynamics may shift down by $10^o-15^o$ the value of $\gamma $
extracted via the overall fit to the $B \to PP $ branching ratios. A
substantial dependence of the fit on their precise values is found,
underscoring the need to improve the reliability of data.
