All of you suggesting permanent life sentences with absolutely no potential whatsoever for release can fuck off with your bullshit, emotivist, victim's rights crusade. Letting your own personal bias affect your judgment when it involves the lives of other people is unnacceptable. The fact of the matter is that the LAST person who should be determining a criminal's sentence is the victim or the victim's family, due to their bias and most likely irrational state.
I've discussed this a number of times before, and before it's even addressed, I'm going to say that I'm fully aware that this will never happen in our society, but it is my view that the prison systems should focus on rehabilitation of criminals first and foremost, and not on punishment. Rehabilitation does not mean imminent release, in any sense of the word. I believe that all inmates should be subjected to a rehabilitary process (excluding prisoners behind bars for crimes that I don't believe merit jail time), and by doing so, this will completely negate the arbitrary sentencing system whereby a judge assigns what comes down to a personally subjective judgment regarding the number of years an inmate should serve. In this process, inmates will be frequently evaluated on their behavior and will not be released until a qualified panel sees that they are fit to return to society and not recommit offenses. In essence, the purpose of this process is to determine that the state of mind of the inmate is altered in which they would no longer believe that it is acceptable to commit crimes, and realize that what they have done is wrong. This process could take anywhere from a couple of months to the rest of their lives. If it so happens that they do recommit, they will most likely be condemning themselves to a permanent life sentence unless it can be determined that the second offense was under justifiably extreme circumstances, whereby they would reenter the rehabilitation process. The vast majority of repeat offenders will likely be behind bars for the rest of their lives because they demonstrated that their evaluations could not be trusted. I would suspect that most murderers, rapists, kidnappers, and other violent criminals will never be released, since they tend to commit crimes with a deluded state of mind that can never be repaired.
