Answer:
According to the Supreme Ruling of 1988 in the case between California v. Greenwood, it was decided that the 4th amendment to the United States constitution does not permit Law Enforcement Agents to seize or search garbage that a suspect left outside of his or her residence without a warrant.
The court's initial argument was that if an individual put out their garbage outside of their house, and in the public, knowing that anyone and or anything could tamper with or rummage it, then there was no reason for such an individual to expect the Law Enforcement Agents to provide a warrant prior to searching such garbage.
Justice Brennan in a counter-argument stated whilst it was true that anyone could have accessed the garbage without the owner's consent, snooping around such behaviour was not exactly one that was reasonably expected of civilised people.
