QM locality

Dear Bruno, Dear All

A few days ago, I was reading one of your (Bruno's) papers (I think it was "Computation, Consciousness and the Quantum"). You wrote that not only the apparent QM randomness is removed by the MWI (this point I understand) but also that QM becomes local if one accepts the MWI. Since then I was thinking about it and I could not resolve all doubt. Locality is quantified by the Bell inequalities. And these inequalities should still be applicable in the MWI since randomness per se will still exist in the many worlds (at least some sort of classical randomness of macroscopic systems). Since you say that by taking the bird perspective on the many worlds, we do not find any nonlocalities, my problem now is, that I do not see how to implement the fact that many worlds exist in order to prove that the Bell inequalities are always fulfilled (i.e. that QM is local). In other words, what is the MW bird perspective Bell inequality? Can someone help me? Are there papers which discuss MWI and locality?

Thanks
Jan
