Chloe would have taken the blame (spoilers)
She was the one wielding the knife. She was also the one who had the motive to kill her ex.
In real life Bobby and Ray probably wouldn't have done any time.
I have to agree.
Also, with the wounds on the two guys it would have been very easy to show that she went nuts and they were trying to subdue her when the accident happened.
On the other hand, she would likely scream "gang rape" and it could go either way.
