In spite of many attempts, no local realistic model seems to be able to reproduce EPR-Bell type correlations, unless non ideal detection is allowed. The low efficiency of detectors in all experiments with photons makes the use of the fair sampling assumption unavoidable. However, since this very assumption is false in all existing local realistic models based on inefficient detection, we thus question its validity. We show that it is no more reasonable to assume fair sampling than it is impossible to test, and we actually propose an experimental test which would provides clear cut results in case of unfair sampling.

A classical model for 'Franson'-type Einstein, Podolsky and Rosen (EPR) experiments is described and compared with alternative, local, realistic models to be found in the literature. A brief analysis is presented which shows that such a model is possible because of unrecognized assumptions in Bohm's reformulation of the EPR gedanken experiment which preclude its use for addressing EPR's challenge.
