Thing is, she was granted good behavior before she even stepped foot into the jail! Under normal circumstances, its after the inmate is in jail for awhile and behaves while he is there. She went from 45 to 23 days for good behavior but she wasn't even in jail yet to exhibit "good behavior".
You know what, to be correct on this, "good behavior" is a STIPULATION of the court during sentencing which NORMALLY means that for a certain amount of time, say a year or 6 months, that person has to be on "good behavior", or an otherwise suspended sentence will be imposed, along with whatever punishment comes with whatever that person did to break the "good behavior". Thats what the courts mean by "good behaviour".
That reduction from 45 to 23 days out of the blue for good behavior was something just pulled out the courts asses. It never happens otherwise normally.
