Is That What Katz is Made Of?
Aya Gruber*
This Article takes the opportunity of the fortieth anniversary of Katz v.
U.S. to assess whether the revolutionary case's potential to provide broad
and flexible privacy protection to individuals has been realized.
Answering this question in a circumspect way, the Article pinpoints the
language in Katz that was its eventual undoing and demonstrates how the
Katz test has been plagued by two principle problems that have often
rendered it more harmful to than protective of privacy. The manipulation
problem describes the tendency of conservative courts to define reasonable
expectations of privacy as lower than the expectations society actually
entertains. The normativity problem captures the idea that the Katz test
allows reasonable expectations to be set by those who engage in
normatively disfavored privacy defeating conduct.  The Article then
concentrates on two specific doctrines exemplary of these problems, the
third party doctrine and the contraband exception, and discusses their
ruinous effects on privacy in a technological era. The third party doctrine,
which roughly holds that third party exposure defeats privacy interests,
has severely hampered the ability of the Katz test to afford Fourth
Amendment protection to intimate online communications. Likewise, the
contraband exception, which holds that there is no legitimate expectation
of privacy in illegal items, proves exceedingly dangerous to privacy as
crime detection technology becomes increasingly refined. In the end,
however, this Article does not advocate trashing the Katz test, but rather
suggests methods of interpretation that remedy the manipulation and
normativity problems.
