Let's flip this plea deal decision on its head for a minute.
What do we think would happen, and in particular, what do we think SG would have to say if the prosecution had declined to offer a plea bargain, one that specified LWOP and no right of appeal, let trial play out instead and then one juror, one as pigheaded as we have seen some people in here be and definitely the wider Internet, decides to vote not guilty?
What do we realistically think would happen then? When the only option Judge Hippler had would be to declare a mistrial, and the whole shebang had to start over, and then it comes out that the prosecution turned down a guilty plea, an admission in open court straight from the horses mouth?
I think everybody here can absolutely understand and empathise with SG, but he is a grieving father who has made it his mission to fight for his daughter for almost 3 years, he has delayed his grief and his healing because its unbearable for him to face it, he has had the distraction of the trial and the single minded focus of the DP to keep him going, and now that is at an end and he has nothing to hold onto to distract from pain that he doesn't want to face.
His feelings are 100% valid, but his methods are not.
The prosecution has done its job, and done it well. Their only goal is to get the best justice they can, and they did that. BK will leave prison in a box, whether the State had eventually killed him or nature does, the outcome is ultimately the same.
