I live in NC.I received four charges in one night three years ago. The charges composed of:Simple assault, assault on a government official, assault on an emergency personnel, and resisting arrest. I had gotten the simple assault charge dropped and I got a differed sentence for the others. Ultimately the charges where dismissed. I want to get these charges expunged off my record. I had also received an underage drinking ticket about 6 years ago. Could I get all these charges expunged? If not which ones? Could I do this myself through the clerks office? Would I need to get a pardon for any?
