The polarization-asymmetry equality for the elastic scattering of spin 1/ 2 particles by unpolarized particles was previously reconsidered and it was shown that in the usual proofs assuming invariance under both space inversion and time reversal the former assumption was unnecessary provided that in the polarization experiment only components perpendicular to the final relative momentum are observed, and that in the asymmetry experiment the beam is polarized transversely to the initial relative momentum. It was then stated that the presence of a longitudinal component of initial polarization would not affect the asymmetry. This is incorrect because in the absence of parity conservation, beams polarized by scattering would in general have such longitudinal components. A method is suggested to overcome this difficulty.
