樓主那case在Fairfax County 想DIY，可能沒有DA會理她。據查：

In Fairfax County, the prosecutors do not typically negotiate with non-attorneys. Plea deals and negotiations happen in side offices outside the courtroom. If you leave the courtroom to try to talk to a Fairfax prosecutor you may be tried in your absence or issued a bench warrant. Additionally, the prosecutors in Fairfax are only given information regarding represented drivers. If a lone driver tries to talk to a Fairfax prosecutor that prosecutor will not have the paperwork or information necessary to get involved.
