Mapp V. Ohio



Dollree Mapp was convicted of possessing obscene materials, after an illegal search, from police, searching for a fugitive.


Thel police search violated the 4th amendment, because they searched Mapp's house without a warrant, making it illegal. However, the "obscene materials" could've been protected by the 1st amendment.


After 6 votes for Mapp, and 3 votes against her, it caused the placement of excluding illegally obtained evidence from court at all levels of the government. Due to the decision, it launched the court on a trouble course of determining how and when to apply the exclusionary rule.
