The use of DNA evidence in criminal investigations has grown in recent years. DNA testing has helped law enforcement identify criminals and solve difficult crimes. On the other hand, DNA evidence has helped prove that many convicted people are actually innocent. Although DNA evidence can be very accurate, there is the danger of the evidence being compromised. Law enforcement must take great measures during the collection process to not contaminate the evidence. Since many crime scenes may have only very small samples of DNA, any contamination of the evidence could jeopardize identifying the criminal and solving the crime.
