Today science, technology, and criminological specialization pervade the criminal process. This evolution has not been without reason. Many of the mainstays of the field of law enforcement have been weakened, and in the process, law enforcement officials have come to rely more and more on science. Modern research has demonstrated an underlying unreliability in regard to eyewitness testimony. Court decisions have limited the use of confessions and altered police procedures regarding interviews and interrogations. Forensic science has emerged into the main arena of the law enforcement process. Like its predecessors, though, forensic science could fall into disuse unless it has the foresight to control and guide its destiny in a better fashion.
