Final Update: So the 24 hours in jail was not terrible... Nobody tried to start shit with me (or rape me haha) but it was just incredibly boring. I was also lucky to not have tweaker cell mates while I was there which coulda made things really bad.
But in response to the post above mine... I'm sure there's some sort of legal action you can take if you just ask a good criminal lawyer about your situation. If you received a deferred charge or they dropped the charge and have not had any more "incidents" for over 11 years AND you had the arrest expunged then nothing should be coming up on background checks... That means that the police department who was prosecuting you has not correctly delt with it and they can be sued over that type of thing. Good luck!
