In order to prevent wrongful convictions, the United States legal system is designed to give the benefit of the doubt to the accused in a criminal case. Put another way, the system is sometimes said to be designed with the thought that it’s better to have a guilty person be acquitted than have an innocent person found guilty. Unfortunately, innocent people are sometimes found guilty, due to any number of reasons, such as the use of unreliable scientific testing, the use of less than truthful witnesses, and attorney error. When all three deficiencies are found in one trial, a person can find themselves incarcerated for a crime they did not commit.
