Features: When DNA evidence is used in court, prosecutors must be able to demonstrate that the DNA has not been contaminated. Care must be taken when handling DNA; crime scenes must be protected, and personnel handling DNA must wear protective gear. Laboratory work must also adhere to strict procedures. Detailed records must be kept, indicating where the DNA evidence is stored and who has had contact with it. DNA data can be used to identify criminals. Similarly, it can also convict suspects and exonerate the innocent. It is a very powerful tool—people's lives depend on it. Sometimes, the only crucial clue is truly a "piece of cake"—or at least for the criminals. Since 1982, fingerprint evidence has helped convict thousands of suspects. However, recent cases have challenged the practice of using fingerprint evidence in court. In law enforcement, fingerprint evidence remains very crucial.
