Did you actually read what you posted. They found that no warrant was required to search the trash.

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.?
[edit]
Obviously you only read the dissenting Judges' opinion.


Anything you put in your trash is not protected by the fourth amendment. This also goes for odors and heat you do not attempt to keep on the premises.

In short: Anything you don't take steps to maintain ownership of is not protected by the fourth amendment.
