I risked up to ten years (theorically) although my lawyer told me the most likely maximum would be five years. I was sentenced to 180 days in a county jail, after accepting a plea deal. What pissed me the most in that story is that the other guy only was charged with a misdemeanor he accepted a plea deal (after he was out of coma, obviously) and only got probation. I was arrested and charged with aggravated assault, a felony in my state. I accept what happened, but will never forgive the society for what happened next. I accept my part of responsibility: I was under adrenaline, I was stressed, a bit angry, and thought everything I would do was self-defense. He is the person who started the fight although I arguably used more force than necessary. I am a white male, straight, currently 33, and merely defended myself. In 2002 I was arrested for participating in a bar fight.
This is obviously a throw-away account, my main Reddit account is in good standing.
I believe ignorance is sometimes better than the truth. This is only the third time I tell this story even my parents aren't aware of it.
