I do agree with your post here and you've put it so well.
My only problem is IMO to be considered "rehabilitated" one needs to be able to accept what they've done and admit to it. Frankly RG still sticking to being in the bathroom while Meredith was killed is simply unacceptable! He should have to fully admit to his active role in her murder, to be considered for any kind of special release.
That is a serious flaw in this system IMO. I do understand the system as it stands he took advantage of the fast track option and like all others is eligible after half his sentence is served. I just disagree that he gets to enjoy any freedoms before he can even admit what he's done.
I have seen his denials of being a thief, drug dealer and drifter. I haven't read a translation of the complete letter. Does he describe the night of the murder in his letter?
