OJ is going to serve at least 4 more years because he was sentenced consectively not concurrently even if he gets paroled on this charge. Sorry but he deserved the chair as he killed those two in cold blood in the heat of passion.
According to our system of justice, you're correct on both counts. Until you find a better way and get everyone else to go along with your changes, you will have to learn to deal with a decision you don't like. Sorry!
