Solving Crimes

          Solving crimes is one of the most importan jobs of law enforcement. Improvements in crime technology help detectives solve crimes faster, and more efficiently, today. Fpr example, crime labs have new kinds of DNA testing, which can identify body fluid such a blood, sweat, and saliva. There are also new kinds of fingerprint testing. In the past, fingerprint testing was only helpful if the fingerprints from the crime scene could be matched with prints that were already on file in police records permanently. People whose fingerprints are not on file cannot be identified in this way, and as a result, many crimes have not been solved.
