The processes $D^0\to K^0 K^-\pi^+$ and $D^0\to\ok K^+\pi^-$ involveintermediate vector resonances whose amplitudes and phases are related to eachother via flavor SU(3) symmetry. A closer look at Dalitz plots for these twoprocesses is expected to shed light on our understanding of the usefulness offlavor SU(3) symmetry in studying charm decays. In the present work we use datafrom the BaBar Collaboration's publication in 2002. The goal is to reproduceDalitz plot amplitudes and phases assuming flavor SU(3) symmetry and comparethem with experiment.  While an SU(3) fit is able to account for the relative magnitudes of theamplitudes for the decays $D^0 \to K^{*-}K^+$ and $D^0 \to K^{*+}K^-$, thecurrent BaBar sample (based on an integrated luminosity of only 22 fb$^{-1}$)provides only 1--$2 \sigma$ evidence for the decays $D^0\to K^{*0}\ok$ and $D^0\to \oks K^0$, with magnitudes and phases not in accord with predictions. TheCLEO collaboration could potentially produce an analysis using data with betterstatistics, and an analysis based on the full BaBar sample (more than 20 timesthe 2002 value) should definitively settle the question.
