Being charged with a criminal act isn't the only time that your life might be impacted by the criminal justice system. You might also find that your life takes a negative turn if you are named as a person of interest in a criminal matter.
In the criminal justice system, a person is considered innocent until it is proven that they are guilty. This isn't the way that things work in real life. Instead, people often form opinions based on limited information that is put out through the media and other outlets. This means that the public might decide that you are guilty of a crime before you are even charged with it.
