Subsequent cases have indicated that what is already in the public domain can be
recorded and disseminated since it would amount to no more than exposing what could
already be seen. For example, in California v Greenwood ((1988) 486 U.S. 35), the
Supreme Court ruled that citizens could have no reasonable expectation of privacy in
items they discarded in the dustbin for the express purpose of having strangers take it
away.
