The Exclusionary Rule is a rule that prohibits law enforcement from using illegally obtained evidence against a defendant in criminal proceedings (Carlson, 2009). This rule was created from the ruling of Mapp v. Ohio, which was a case between a woman named Dollaree Mapp and the State of Ohio (“Mapp V Ohio,” n.d.). Because of the Exclusionary Rule, law enforcement must make sure to correctly follow certain procedures in order to be able to present all the evidence obtained from a crime scene in a court of law.
Basis for the Exclusionary Rule
The concept of the exclusionary rule was first established in the United States Supreme Court ruling of Mapp v. Ohio. In this case, the Cleveland Police Department entered the residence of Dollaree Mapp to search for a wanted fugitive that was believed to be hiding in Mapp's home (“Mapp V Ohio,” n.d.). While searching for the fugitive, Police found books containing lewd material. After discovering the books, police arrested Mapp but never charged her with anything (“Mapp V Ohio,” n.d.). Mapp claimed that the seizure of evidence in her case violated the fourth amendment protection from unlawful search and seizure (“Mapp V Ohio,” n.d.).
