Today, law enforcement can identify suspects by using disciplines based on scientific principles. Scientists use two main techniques—fingerprint comparison and DNA an
alysis—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.)
