My son is 24 and has Aspergers Syndrome. He pleaded guilty to two misdemeanors in return for dropping two absurd felony charges Any expungement now?

He has gone through a living hell with rental agents, volunteer job reviewers, school admissions, employment reviews, etc. Our lawyer at the time told us it was the safest way to compromise. In hindsight, this advice was beyond bad. My son was apprehended,had his head held to the gournd by an officer''s boot, after inadvertantly scratching him. He was thrown in a squad car and could not settle down from lack of medication. He was threatened to be tazered in the back seat and in fact was shot in the sneaker. He feared for his life and knocked out a window. The scratch and police car damage resultied in two "felonies"/ Is there a way to file a writ of actual innocence or a pardon with the governor to clear his name and frankly my family''s? As a handicapped citizen he has suffered and so have we.--State of Virginia
