It was shown that, contrary to some authors opinion, the polarization effects observed recently in low-intensity light interaction with $\bar{4}3m$-class crystals (GaAs, InSb) did not point to any violation of the symmetry principle for kinetic coefficients in these crystals, since these effects are mainly caused by near-surface nonuniformity of their optical properties. Polarization effects were indicated which, if observed, would actually confirm the symmetry principle violation of these crystals kinetic coefficients.
