In criminal law the principle of the presumption of innocence until proven guilty is sometimes distorted and altered into the presumption of guilt until proven guilty in many cases of unjust conviction. Many factors go into the deliberation and reasoning behind the verdict of detectives, juries and courts, and occasionally their decision is actually wrong and an innocent person is thrown behind bars, serving a sentence they don't deserve because they are not a criminal . False confessions from an innocent suspect are very common in the interrogation room and it is their fault because they admit to taking part in a crime they were honestly not a part of due to misleading questions or statements from investigators. Another factor that could put an innocent person in prison is incorrect scientific findings and false DNA evidence. Doctors sometimes misinterpret injuries and causes of death, and this can significantly alter the outcome of a case. Finally, witnesses may report false sightings or report something they thought they heard but misinterpreted. More laws should be put in place to protect innocent suspects and to ensure that no one goes to prison who really doesn't deserve it and more citizens should be trained to give an accurate description of a suspect to decrease the rate of wrongful convictions. it's understandable why a criminal would lie about committing a crime to get out of trouble and stay out of prison. In most prisons around the world, 90% of convicted criminals maintain their innocence. Many people find themselves in the opposite situation when they are accused of a crime they are unaware of or connected to and police officers or investigators profile them based on previous cases… middle of paper… The people are not punished for a witness's mistake. A wrongful conviction is the worst thing a jury, witness, investigator, or judge could be responsible for. The weight and guilt that will fall on their shoulders, knowing that an innocent person had to spend time outside of their personal life in prison is unbearable. No one is perfect, but everyone should try to get as close to perfect as possible when they put a person in prison for a crime they are sure they committed. Compensation will help the innocent victim who had to waste time in prison, but nothing will replace the time lost away from families and many families get angry and hate the person thrown into prison because they thought he was really guilty, little to their knowledge of their innocent. Sometimes money can buy happiness, but it can't replace lost love and time wasted in prison.
