Casey was entitled to time off for good behavior. She got it. I have no problem with it.
My only real issue with Judge Perry was with sentencing on the lying convictions. His sentence for lying were one year on each count, to be served consecutively, but then for reasons I cannot fathom, he allowed those consecutive terms to run concurrent with a sentence that had by then already been served. That made no sense to me and it still doesn't make sense to me.
Casey should have been sentenced to four consecutive years on her four lying convictions, period. From that four years, she would get credit for time she had been in jail awaiting trial, plus time off for good behavior at whatever percentage the law allows. But the first 412 days of Casey's total time in jail up to that point should not have been counted when imposing the lying sentences, as that 412 days was her sentence on the separate fraud convictions. And it had already been served! It's not like she was still serving that sentence at the time the new sentence was imposed. Even then I would have not wanted it run concurrently but it would have at least made a bit of sense.
I have never understood the wisdom behind consecutive sentences (when it could just as easily have been concurrent) only to have that consecutive term run concurrently with totally unrelated convictions, more than a year after that sentence had been served.
