Abstract
Pitowsky's deterministic model of electron spin is considered from the point of view of locality. Two possible formulations of the model are distinguished, and for each an argument is presented showing that it cannot locally model the singlet spin state as it arises in the EPR and Bell experiments. These arguments are based on an adaptation of Herbert's proposal for superluminal communication in quantum mechanics. This adaption is not subject to the proofs refuting Herbert's scheme. The second argument suggests that the model is in fact incoherent as a physical theory.
