We have considered a two-particle Bell experiment to visualize the conflictbetween rotational invariance of physical laws and a specific local realistictheory. The experiment is reproducible by using a local realistic theoryobtained in a two-setting Bell experiment. The generalized Bell inequality {[J.Phys. A: Math. Theor. {\bf 40}, 13101 (2007)]}, which is derived under theassumption that there exists a rotationally invariant local realistic theory,turns out to disprove such a local realistic model existing with a two-settingexperiment. This implies that such a model is not rotationally invariant andshould, therefore, be ruled out in some situations.
