  We show that the superluminal muon neutrinos in the recent OPERA experiment
can exist theoretically. The refutation of the OPERA experiment from some
theoretical arguments is not universally valid, but resulting from some
implicit assumptions. Our argument can accommodate both the OPERA experiment
for superluminal neutrinos and the ICARUS experiment of no evidence for the
analogues Cherenkov radiation of muon neutrinos from CERN to the LNGS.
