Hey Mike this is David Uwate. I met you in Tunica.
This is a very common plea deal for first time offenders or in cases where there are evidentiary issues. Seeing as you say you have him on video, walking with the cues, my guess has to be that he was offered this due to his lack of prior record and not to problems with securing a conviction from the evidence.
In non violent crimes, especially where the victim has been made whole again via recovery of stolen property, it is commonplace to see Judges and prosecutors resolve those cases without consulting with the victims. I realize this leaves a bad taste in your mouth but consider that to these cogs in the justice system wheel, this case is one of many where there are asked to either dedicate resources towards a trial or plea the case down to a mm and its resolved with a criminal conviction of theft on the defendants record. Think about it, if they had offered him 9 mos in jail to plea, he would have plead not guilty, bonded out and this would be a likely trial. Defendants who are offered sentences that are in upper reaches of where they would get the same sentence were they convicted at trial have nothing to lose by going to trial. To the Judge and prosecutor, they would rather dedicate the resources towards putting violent repeat offenders in prison.
As far as your rights as a victim, one thing you can do is call the prosecutor and ask that the defendant be adjudicated guilty of the mm theft charges. In many states an adjudication of guilt will be discoverable on background checks and is asked on job applications. Getting his record sealed and expunged on an adjudication of guilt is also much harder than if he is given a withhold adjudication of guilt.
