brain storm justice Kristy

I believe without justice the world would be a jungle where the strongest will eat the weakest. When a person has a problem they will hire a lawyer to defend them in court. Unfortunately, most of the time the judges and the juries are not fair; they will judge the innocent as guilty and sentence him or her to jail. At the end and after somebody from the defendant family succeed in reopening the case again, or when they find the right one who commits the crime. Then they free the innocent one from jail. But that poor person lost many years from his/ her life behind bars. Is the juridical system fair by locking him/her behind bars?
