  In this work we analyse critically Griffiths's example of the classical
superluminal motion of a bug shadow. Griffiths considers that this example is
conceptually very close to quantum nonlocality or superluminality,i.e. quantum
breaking of the famous Bell inequality. Or, generally, he suggests implicitly
an absolute asymmetric duality (subluminality vs. superluminality) principle in
any fundamental physical theory.It, he hopes, can be used for a natural
interpretation of the quantum mechanics too. But we explain that such
Griffiths's interpretation retires implicitly but significantly from usual,
Copenhagen interpretation of the standard quantum mechanical formalism. Within
Copenhagen interpretation basic complementarity principle represents, in fact,
a dynamical symmetry principle (including its spontaneous breaking, i.e.
effective hiding by measurement). Similarly, in other fundamental physical
theories instead of Griffiths's absolute asymmetric duality principle there is
a dynamical symmetry (including its spontaneous breaking, i.e. effective hiding
in some of these theories) principle. Finally, we show that Griffiths's example
of the bug shadow superluminal motion is definitely incorrect (it sharply
contradicts the remarkable Roemer's determination of the speed of light by
coming late of Jupiter's first moon shadow).
