  The following is a comment on the recent letter by Iocco et al. (2015,
arXiv:1502.03821) where the authors claim to have found "...convincing proof of
the existence of dark matter...". The letter in question presents a compilation
of recent rotation curve observations for the Milky Way, together with
Newtonian rotation curve estimates based on recent baryonic matter distribution
measurements. A mismatch between the former and the latter is then presented as
"evidence for dark matter". Here we show that the reported discrepancy is the
well known gravitational anomaly which consistently appears when dynamical
accelerations approach the critical Milgrom acceleration a_0 = 1.2 \times
10^{-10} m / s^2. Further, using a simple modified gravity force law, the
baryonic models presented in Iocco et al. (2015), yield dynamics consistent
with the observed rotation values.
