Today, law enforcement can identify suspects by using disciplines based on scientific principles. Scientists use two main techniques—fingerprint comparison and DNA analysis—to determine whether the fingerprints or DNA samples found at a crime scene match those of a suspect.

• Give historical information about each technique. List the uses and functions of these techniques.
• Explain the limitations of each technique.
• Explain how these techniques can be challenged in court. (Refer the Argosy University online library and/or the Internet.)
