  The OPERA collaboration has announced to have observed superluminal neutrinos
with a mean energy 17.5 GeV, but afterward the superluminal interpretation of
the OPERA results has been refuted theoretically by Cherenkov-like radiation
and pion decay. In a recent work, we have proposed a kinematical resolution to
this problem. A key idea in our resolution is that the OPERA neutrinos are not
superluminal but subluminal since they travel faster than the observed speed of
light in vacuum on the earth while they do slower than the true speed of light
in vacuum determining the causal structure of events. In this article, we dwell
upon our ideas and present some concrete models, which realize our ideas, based
on spin 0, 1 and 2 bosonic fields. We also discuss that the principle of
invariant speed of light in special relativity can be replaced with the
principle of a universal limiting speed.
