If you live in Greenwood, Laurens, Newberry, or Abbeville Counties, go to the http://www.scsolicitor8.org/ website, click on "diversion programs", then "expungement" and follow the instructions. If you live in McCormick, Saluda, or Edgefield, you will need to call the 11th Circuit Solicitor's Office at(NNN) NNN-NNNN obtain the proper forms, and set an appointment with someone in the office.
Well, the "application process" tab under the "How does it work" tab is about as specific as you can get with step by step numbered instructions. It is just a matter of you filling out the form and submitting it along with any fees to the Solicitor. If you meet the statutory requirements, then you get it expunged. If not, then you don't.
As for your other case, law enforcement tends to "circle the wagons" and defend their own, sometimes getting into the grey/black areas of the law in doing so.
But the expungement is a yes/no decision as to whether you qualify.
