Crime vs. Punishment

Crime and punishment seem to go hand in hand. However, I think sometimes the punishment given to the crime is unjust. I mean that if someone murdered someone and another person was caught on possesion charges, and the person with possesion recieved a longer sentence than the murderer that isn't right. I understand the world isn't fair, I think though the punishments given should be thought over before being given. Sometimes people are wrongly accused of a crime they did not commit, and are put in jail. Technology has helped us in over the past thirty years though to keep this from happening more frequently. The criminal justice system is getting better, but we all need to learn not to overlook any little bit of evidence recieved.
