If the officer did not charge you in the field it is highly unlikely that he will charge you later. Even if he did the DA would have to conduct an investigation before a case could be filed and it is probable that based on these facts your case would be rejected.
Above all do not go to the police station to talk to the cop. Do not call the DA to see if charges have been filed. Do not pay an attorney a pile of money when you probably won't need him anyway.
You should learn that...
You need to be more specific about what comes out on your record. Normally when someone is acquitted of all charges they will still have the arrest on their record and the final disposition. Getting this off your record is difficult. I suggest you contact an attorney about a PC 851.8 petition for factual innocence which, if granted, would seal everything.
My Chicago friend seems unfamiliar with practice in CA. The kind of diversion you are talking about does not require the entry of a guilty plea and will allow him to avoid a criminal record. A guilty plea can only be entered in court so if there are no court appearances and your bf was not arrested he should come out of this with no record at all.
You are under no obligation to pay the civil demand from the store. Not paying will have no effect on any criminal action against you. The store cited PC 490.5 because that statute allows the store to demand up to $500 for each shoplifting incident. The key word is "demand." It is not an obligation and certainly not a fine that you must pay.
It is not possible to say what statute the DA will use. If the amount was under $50 there is a good chance it will be 490.5 which can befiled either...
Your son deserves the very best legal defense available. If you feel that his (appointed?) lawyer is not giving him this, then your son should take the initiative and demand a meeting with the lawyer. It may be that this can be resolved. If the lawyer refuses your son should demand a meeting with his supervisor. All of this should be done before your son approaches the Court for relief. You should know that the lawyer has no obligation to you so it is up to your son to take these steps.
Four beers on July 4th won't show upon any test today. But in your last question you said you had been drinking Friday night too. That also should be gone. But now the question is what happened last night?
Cases involving both a federal and a state sentence are complicated and require an attorney's help, which you have. Given that you have an attorney I don't understand why you are asking questions on the Internet about the deal he is structuring. I agree with my colleague that it would be inappropriate for us to second guess him.
A procedural issue of great importance to parties accused of conspiracy is whether government prosecutors try to frame the conspiracy as a "hub-and-spoke conspiracy" or a "chain conspiracy." In a hub-and-spoke conspiracy, many parties (the spokes), conspire with one person (the hub), but not with other defendants. It is advantageous for a defendant to have its actions characterized as part of a hub-and-spoke conspiracy, because that means that the conspiracies are separate and disconnected....
