William O. Douglas,
Cooper v. California — Dissent
“ There are those who do not like Preston. I think, however, it states a healthy rule, protecting the zone of privacy of the individual as prescribed by the Fourth Amendment. These days police often taken possession of cars, towing them away whem improperly parked. Those cars are 'validly' held by the police. Yet if they can be searched without a warrant, the precincts of the individual are invaded and the barriers to privacy breached. Unless the search is incident to an arrest, I would insist that the police obtain a warrant to search a man's car just as they must do when they search his home. ”
