My daughter will be an 18-year old freshman at UA in a few weeks. I'll tell her what I'd tell her if she was dating anyone on campus. Be smart. Try avoiding putting yourself in a bad situation. And don't be afraid to fight, yell, scream, before, during, and after is something bad does happen.
The reality is, JDL isn't the only guy on campus with a Juvie record. And statistically, he's not the only guy with a Juvie assault record. The difference is JDL has NIL monies and makes him worth suing in a civil case, versus the regular college junior who has significant student debt, and is living off of cereal and ramen. This is why we know about JDL's record, but not all the others on campus who may have a similar past.
Criminally speaking, JDL's adult record is clean. He's also one of the more high profile athletes on campus. And given the settlement news, any false step and not only is he gone from Arizona forever, he might never play college ball again.
