battery charge Criminal Records, Expungement

You need to understand that any expungment will not TOTALLY conceal or even remove the stain your actions have placed upon your record.
The diversionary program simply allowed you a chance to stay out of jail.
Only a full pardon can allow you to say you were never convicted of anything.
Don't delude yourself for one minute that after you get off of probation that no one will ever know that you were arrested, plead guilty, served your debt to society, and remained a free citizen.
The benefit of these programs are to the government.
If the authorities didn't allow some to stay out of jail or prison, there would be no where to lock up all of the unfortunate people convicted of crimes.
