[TX] When I was 16, I was charged with 2nd degree assault, and I failed to appear in court, and then turned 17. After turning 17, I received a letter that gave me the options to plead guilty or no contest to my charge. I wasn't thinking straight, and I let my ex-stepfather make the decision for me, and I don't remember which option he circled, but I signed my name as if it were my decision. Do I have to reveal this charge to potential employers/scholarship opportunities/colleges, and who can see this charge? Was I legally tried as an adult because I was 17, and did I miss out on my chance for some sort of legal representation? Can I get this off my "record?" PS, during the charge I talked to the officer and admitted guilt, but I was never read Miranda rights, and the officer included details in the report that didn't happen, would it be difficult to prove the officer included things that didn't happen, and does me not having been made aware of my rights change anything?
