The United States Supreme Court has long recognized the value of scientific evidence – especially when compared to other types of evidence such as eyewitness identifications, confessions, and informant testimony. For example, inEscobedo v. Illinois, the Court observed: “We have learned the lesson of history, ancient and modern, that a system of criminal law enforcement which comes to depend on the –confession— will, in the long run, be less reliable and more subject to abuses than a system which depends on extrinsic evidence independently secured through skillful investigation.” Similarly, inDavis v. Mississippi, the Court commented:Detention for fingerprinting may constitute a much less serious intrusion upon personal security than other types of police searches and detentions. Fingerprinting involves none of the probing into an individual's private life and thoughts that marks an interrogation or search. Nor can fingerprint detention be employed repeatedly to harass any individual, since the police need only one set of each person's prints. Furthermore, fingerprinting is an inherently more reliable and effective crime-solving tool than eyewitness identifications or confessions and is not subject to such abuses as the improper line-up and the “third degree.”
