DNA testing has created a whole new level of confidence in identifying criminals. Human DNA is specific to each individual, which makes it the perfect way to tell exactly who left the DNA evidence at the crime scene. If detectives can prove someone was at the scene, they can put together a better case.
Better Than a FingerprintFingerprints have been the most popular way to identify people at crime scenes for centuries. They are not foolproof, however, and can be covered up by gloves. Fingerprints can also be altered in extreme situations by surgery or burning the fingertips. DNA evidence is not so easy to cover up. People lose DNA molecules accidentally just by moving around. Human hair falls off without being noticed. A single strand of hair contains enough DNA to identify a person with very little margin of error. It is impossible for a person to alter their own DNA, so hiding from a DNA test is not an option.
Not Admissible in all SituationsSince DNA technology is relatively new in law enforcement, there are some legal situations in which it is not admissible in court. The courts have not been fully convinced of the infallible nature of DNA testing. Time and better testing techniques will likely lead to all courts accepting DNA evidence for all cases in which the DNA was obtained in a lawful manner. DNA that is obtained through unlawful tactics is not admissible in any court for any reason, which means that law officers need to be careful in the way they collect their samples.
Proving Innocence of ConvictsHigh profile cases involving DNA testing for old crimes have been very popular in the news in recent years. Several cases have used DNA evidence to prove that the person who was convicted of the crime was actually innocent. This has raised some serious questions about the way the legal system works, especially regarding capital punishment. When several people are proven to be innocent even though they were convicted of the crime it is difficult to condone killing someone for a crime that they say they did not commit. As DNA testing becomes more prevalent there is a chance that criminal convictions will become more accurate.

DNA tests are not conducted for all murder suspects, but they are increasingly common in homicide investigations, especially when biological evidence is available at the crime scene.

Additionally, legal protocols and resources can influence whether DNA testing is pursued in a particular case. Ultimately, the decision to conduct DNA tests depends on various factors, including investigative strategy and the specific evidence at hand.
