What are my options? Can I do Pretrial Diversion?

A minor theft charge like that, espcially if it is your first time, sometimes gets resolved by a "deferred sentence''. That is a plea bargain where if you plead guilty at the beginning and agree to abide by certain conditions over a time period, then in the end, the guilty plea is withdrawn and the charge is dismissed so it does not end up with a conviction. The probation might be 12 months. The conditions might be that you attend a 'theft' class, do community service work, not violated the law, pay various costs, etc.
