DNA fingerprinting is available in any crime where a suspect leaves behind DNA. It offers a precise identification and requires only a small amount of evidence. When admitted as evidence, it could reduce the importance of eyewitness testimony. Its main use may be in sex offenses. However, procedures have not yet been developed that standardize the use of DNA evidence in court proceedings. The history of problems related to other scientific techniques demonstrates the importance of avoiding its premature admission into evidence. Once DNA testing becomes routine, it will save money, shorten investigations, and increase conviction rates. Until that time, courts should be careful when using it to assure its continued use and reliability. Footnotes (Author summary modified)
