I remember the olden days, those that came before the victims and their friends/families/witnesses could stand in the court and cry 'for shame!'. It was made a political football because a wave of the technocrats and activist judges have taken over the court system. There were quite a few 'shocking' examples of light plea deals for capital crimes-(no real mention of if the DA had enough solid evidence to convict on a 'heavy' charge and if not the perp could walk scot free) As well as light sentences for crimes an outraged citizenry decried.
So laws were passed to give the victims and families a chance to stand and shame the perp, as well as being informed of a possible plea deal- I think some call it 'signing off' before it is offered.
Now it appears we are cycling back away from wailing parents and grieving spouses being part of the official process.
What's old is new again I suppose.
More than a few defendants attempt to back out of plea deals, they listen to fellow inmates- now that's a great brain trust- others locked up often for being guilty of more stupid than crime! And buyer's remorse is for more than new cars and spouses, afterall solid and clear decision making isn't always part of a criminal's make-up. I can see some of them wanting to blame everyone but themselves at such times.
Now on assigning cost of prosecution to the defendant. Here in Oklahoma you can go online and see the defendants and their status in the court system. They also list the fees assigned to the defendant. Cost of lab work and a staggering amount of court costs, judge retirement fund, victim impact fund, and the beat goes on for quite a bit. I don't know if at trial the expert fees are paid for by the defendant, but have heard DAs complain the costs of trial, and that includes witnesses is draining the funds available for trail.
Is a rather silly dance to assign the costs to defendants, most are never going to pay the fees, the options are keep sending them back to prison where they clog up the system- (most just get a weekend in jail and then OR'd) or have them pay 20 bucks a month forever. (most pay 20 bucks when ever, serving petty thieves and drug users with a constant barrage of warrants would exhaust local county LE.)
Society asked for the victim to be part of the plea/sentence part of the system.
Will be interesting if they change their minds.
