Through Bell's inequality, we can see that any hidden variable theory of QM will have to satisfy the inequality, but as it doesn't, wave function must be the whole story and so we have to do away with realism. So when a measurement is done on one detector in the EPR experiment, the wave function collapses for both the observers simultaneously and so locality must also be violated. So in this sense, by violation of realism, locality is also violated as a consequence. So i was wondering if they imply each other or i am misunderstanding something here since i have read in some books that they do not necessarily imply each other.
