Use of Forensic Evidence in Criminal Cases Since the beginning of time, people have been committing crimes and put on trial. Even Jesus had a trial and the people decided whether or not to execute him. With new technology becoming available every day, there are new ways to convict criminals. However, there are many flaws in the judicial system to the point that even the use of DNA evidence isn’t enough to prove someone’s innocence.

The problems that came from this are pretty apparent, but sketches are still used today, more for the public knowledge, rather than a way to convict someone. Then with the invention of cameras, photographs were used as evidence. However, this meant that someone had to be at the crime scene to take pictures. The criminal could also change their looks, or wear a disguise to try to claim innocence. Then came the knowledge of using fingerprints.

It was then discovered that there is a gene mutation that erases fingerprints, and so some people don’t have them. The criminal could also wear gloves so that they wouldn’t leave their prints behind. With the technology to read DNA and match it to a person, it is impossible to not know exactly who committed the crime. Everyone except identical twins have different DNA. It is impossible to change your DNA, so this is the best way to prove either innocence, or guilt. The most common places to get DNA evidence from a crime scene is blood, semen, saliva, urine, or hair. Police and detectives that work on murder crimes (for instance) search the surrounding area for clues that could lead them to DNA that the criminal could have left behind, whether it come from a cup that they drank from, a cigarette butt, or semen if it
