  We revisit the Hall effect and magnetoresistivity by incorporating the
anisotropic scattering caused by apical oxygen vacancies in overdoped La-based
cuprates. The theoretical calculations within the Fermi liquid picture agree
well with a handful of anomalous magneto-transport data, better than the
results using an isotropic scattering rate alone. In particular, we obtain the
upturn of Hall coefficient $R_H$ with decreasing temperature $T$, the initial
drop of $R_H$ in magnetic field $B$ in all overdoped regimes, the linear
resistivity $\rho$ versus $B$ near the van Hove doping level, the temperature
dependence of the magnetoresistivity ratio, and the violation of Kohler's law.
These results suggest that many of the anomalous transport behaviors in
overdoped La$_{2-x}$Sr$_x$CuO$_4$ could actually be understood within the Fermi
liquid picture.
