Her presidential campaign appears to be fully fecked, and her personal freedom very likely will go with it. The State Department was asked by FBI to stop its internal investigation & let FBI do its thing. FBI is getting ready to bring the hammer down, and hard. Hillary is going to squeak like a little mouse & croak.
I guess the burden would have been on prosecution's side to show Z's actions strongly suggested sexual molestation as his intent. Based on the 911 call, it's clear Z was following him for a different reason.
If Trayvon wrongly thought Z was about to molest him, does that take away Z's right to self-defense? Is Z held responsible for the wrong conclusion drawn by Trayvon? I don't know. We'd have known if prosecution went this route.
I don't actually think Trayvon thought anything like that. Almost every black person I talked to about the case thinks Z racially profiled Trayvon, and Trayvon had a genuine grievance when he confronted Z. It looks more likely that Trayvon thought so too.
