Forensics in the Criminal Justice SystemThe criminal justice system has changed a lot since the good old days of the Wild West, when just about everything was legal. Criminals were dealt with in whatever manner law enforcement deemed appropriate. The science of catching criminals has evolved since those days. We are better than ever at catching criminals and we owe this progress to forensic science. The development of forensic science has given us the important techniques of fingerprinting and DNA analysis. We can use these techniques to arrest criminals, prove people's innocence, and track inmates after they are released on parole. There are many different ways to solve crimes using forensic evidence. One of these methods is to use blood spatter analysis; this is where the distribution and configuration of bloodstains are studied to determine the nature of the event that caused the blood spatter. Many elements come into play in determining cause, including: the effects of various types of physical forces on the blood, the interaction between the blood and the surfaces it falls on, the location of the person spilling the blood, location and actions of the attacker. , and their movement both during the incident. Another common type of forensic evidence is trace evidence. This is usually recovered from a number of items at a crime scene. These items may include carpet fibers, clothing fibers, or hair found at or around the crime scene. Hair recovered from crime scenes can be used as an important source of DNA. Examination of items recovered from a victim's or suspect's clothing may help establish an association between the victim and other people, places, or objects involved in the investigation. DNA analysis is the most important part of forensic science. DNA evidence can take many forms at crime scenes. Some of these shapes include hair; bodily fluids recovered from the crime scene or from the victim's body, skin under the victim's nails, blood and many others. This DNA can be the basis of a person's guilt or innocence; she decided many cases in the 20th century. As times change and criminals get smarter, we will always need to find new ways to catch them. Forensics is the most advanced method to date, but it's just the beginning. As the scientific field develops, the capabilities of
