Interesting that Einstein's proposal with modified Malus's law for single photons produces a "local realism" explanation for the observed apparent Bell's violation in photon polarization experiments. At the Einstein's time they didn't have single-photon counters to confirm/deny, and today it seems that single-photon Malus looks like the classic one (though i didn't find articles directly confirming it, only other articles mentioning it as confirmed). Nevertheless, possibility that such reasonably looking variation of the pretty empirical law produces "local realism" explanation makes me believe that "local realism" battle is far from lost yet :)
