While others have defined justice outside of the court system, my definition of justice has to stay within. I believe that with justice, there is always punishment for your actions or in other words, I believe justice in the criminal sense. With justice there is always punishment. Punishment is to make the situation at hand fair to both the accuser and the accused.
Take for example Lawrence Russell Brewer, he was executed Wednesday for his involvement in the dragging death of a black man 13 years ago. Him and two others kidnapped a man and chained him to the back of a pick-up truck. They dragged him for three and a half miles until he was decapitated when he hit a culvert. In my opinion, justice was served. Lawrence deserved to be executed for his behavior. To have Lawrence executed would reassure the man's family that he would never commit such a crime again and not only that, he would not be eating up the taxpayer's money.
Punishment will always be involved in justice, just not always to the extent of execution. I believe that justice should be just like Newton's third law of motion: For every action, there is an equal and opposite reaction. Lawrence took the life of an innocent man, we take his. To keep him alive would have been a waste.
