I know a person who got raided from what they found in his trash. It is not legal but they lost there house from it.

Here is a way to beat the case if it does happen.

California v. Greenwood, 486 U.S. 35 (1988)[1], was a United States Supreme Court case that held that the Fourth Amendment does not prohibit the warrantless search and seizure of garbage left for collection outside the curtilage of a home.

Background

In early 1984, Investigator Jenny Stracner of the Laguna Beach Police Department learned from various sources that Billy Greenwood might be selling drugs out of his single-family home. In April, Stracner asked the neighborhood's regular trash collector to pick up the plastic garbage bags that Greenwood left on the curb in front of his house. In the garbage, she found evidence of drug use. She used that information to obtain a warrant to search Greenwood's home. When officers searched the house, they found cocaine and marijuana. Greenwood and Dyanne Van Houten were arrested and released on bail.

In May, another investigator again had the garbage collectors pick up the garbage bags left on the curb. The garbage again contained evidence of drugs, the police obtained another search warrant, and they found more drugs and evidence of drug trafficking in the house.

The California Superior Court dismissed the charges against Greenwood and Van Houten on the ground that warrantless trash searches violated the Fourth Amendment and the California Constitution. The Court of Appeal affirmed. The California Supreme Court refused to hear the appeal.

Decision
By a 6-2 vote (Justice Kennedy took no part in the case), the Court held that under the Fourth Amendment, no warrant was necessary to search the trash because Greenwood had no reasonable expectation of privacy in it. Although Greenwood had hidden the trash from view by putting in opaque plastic bags and expected it to be on the street only a short time before it would be taken to the dump, the Court believed it to be ??common knowledge? that garbage at the side of the street is ??readily accessible to animals, children, scavengers, snoops, and other members of the public.? Moreover, Greenwood had left the trash there expressly so that the trash collector, a stranger, could take it. Quoting Katz v. United States, the court concluded that "[w]hat a person knowingly exposes to the public, even in his own home or office, is not a subject of Fourth Amendment protection."

Greenwood also argued that the evidence should be excluded under the California Constitution, which the California Supreme Court had interpreted to prohibit warrantless searches of garbage left at the curb. An amendment to the California Constitution, however, had eliminated the exclusionary rule for unconstitutionally obtained evidence. The Court rejected Greenwood??s claim that the amendment violated the Due Process Clause. It held that so long as the police conduct did not violate federal law, ??California could permissibly conclude that the benefits of excluding relevant evidence of criminal activity do not outweigh the costs.?

Dissent

Justice Brennan reasoned that the possibility the police or other ??unwelcome meddlers? might rummage through the trash bags ??does not negate the expectation of privacy in their contents any more than the possibility of a burglary negates an expectation of privacy in the home.? Under United States v. Chadwick, the bags could not have been searched without a warrant had Greenwood been carrying them in public. Merely leaving them on the curb for the garbage man to collect, Brennan argued, should not be found to remove that expectation of privacy, for ??[s]crutiny of another's trash is contrary to commonly accepted notions of civilized behavior.?
