@Alchemy- I am not sure what states offer deferred sentences, but I know that not all states offer deferred sentences because not all states allow records to be expunged (I assume anyway). I did a little bit of a web search, reading mostly legal forums, and I found that a deferred sentence is not always as cut and dry as it may seem. From what I read, some states offer a deferred sentence, but once the convicted completes his or her sentence, he or she finds it nearly impossible to have his or her record sealed.
I was actually reading that a number of rights groups are advocating for better defined rules for deferred sentencing. It seems like the more progressive states actually expunge all records once a sentence has been deferred while states that are more conservative treat deferred sentences more like suspended sentences. If you are facing charges and trying to seek a deferred sentence, find a good criminal defense lawyer that is trustworthy to guide you through the process.
