Here's the problem, when people say, "face the consequences", they aren't actually realizing that this kind of thing follows a kid like him too far in his life. You fucked up, you had a lapse in judgement, should you be fined etc? Yes. Should this affect you years down the road? No. Sadly our judicial system has flaws, everything is looked as punishment, there is more too it, the entire point of justice is not just punishment but the feeling that doing the same thing again isn't right but we as Americans are taught that all you deserve is punishment. This is where I believe we are wrong, justice should as be considered an opportunity to rehabilitate (depending on how bad the crime was and how long you might be in) as well.
I'm just hoping this doesn't end up too badly for you considering you're 18 and your friend was 17 at the time. Something like this should not follow you after college for job interviews and I sure hope it doesn't, I already think the American judicial system is a bit too harsh in the first place.
