The Fourth Amendment to the Constitution states that people have the right “to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures,” but the issue at hand here is whether this also applies to the searches of open fields and of objects in plain view and whether the fourth amendment provides protection over these as well. In order to reaffirm the courts’ decision on this matter I will be relating their decisions in the cases of Oliver v. United States (1984), and California v.

United States, and reversing the case of Thornton v. Maine, and in essence reaffirming that
