Hmm, I’m a zero in United States law, too.
But logically speaking, she’s just a student with a shitty background, a shitty dad, but she’s still just a student.
And Burke is the fucking dean, first of all, he’s got a lot of influence and all, he could have gotten Quinn to set up a brothel and distribute drugs.
His crimes are also logically more serious than hers.
He’s not just covering it up, he’s using it for his own purposes.
And from the perspective of a career-wise detective or an FBI agent, (I don’t know who should be investigating these cases ) apparently, arresting an unnamed college student won’t give a boost, but making her a witness and all the girls who took part in it will put Burke away, It’s a huge career boost. Any sensible person would choose to put him away instead of Quinn, even if she were given time for cooperating with the investigation, she would be given serious leniency, possibly probation.
But yes, I don’t know the laws of the United States, but logically, what I said makes sense.
