  We entertain the idea that the uncertainty relation is not a principle, but
rather it is a consequence of quantum mechanics. The uncertainty relation is
then a probabilistic statement and can be clearly evaded in processes which
occur with a very small probability in a tiny sector of the phase space. This
clear evasion is typically realized when one utilizes indirect measurements,
and some examples of the clear evasion appear in the system with entanglement
though the entanglement by itself is not essential for the evasion. The
standard Kennard's relation and its interpretation remain intact in our
analysis.
  As an explicit example, we show that the clear evasion of the uncertainty
relation for coordinate and momentum in the diffraction process discussed by
Ballentine is realized in a tiny sector of the phase space with a very small
probability. We also examine the uncertainty relation for a two-spin system
with the EPR entanglement and show that no clear evasion takes place in this
system with the finite discrete degrees of freedom.
