Is legal protection an effective countermeasure for privacy intrusion? Explain the difficulties or efficacy of using the law to provide privacy protection

What will be an ideal response?

While
legal
protection
is
somewhat
useful,
the
primary
problem
is
that
the
victim
often
has
no
way
of
knowing
when
his/her
privacy
has
been
violated,
as
it
often
happens
on
a
computer
system
that
the
victim
will
never
even
know
exists.
Another
problem
is
the
vague
and
context-­?dependent
distinction
between
private
and
non-­?
private
information.
