Universities punish students all the time for things that law enforcement would decline to prosecute. I don't understand why that is even an issue here.
Title IX does not require due process and it doesn't even require proof beyond a reasonable doubt. I work on a college campus and we have Title IX "training" twice a year. According to our Title IX coordinator, regarding sexual misconduct, all that is require is a conclusion that the accused more then likely did something wrong and the school can kick the student out. It is all on the accused to prove his/her innocence, at universities guilt is assumed first. I don't agree with these policies, it gives way to much power to someone falsely accusing a student, but I've been in these meeting for 3 years and this stuff is explained every time.
Minnesota doesn't have to prove anything, they just have to suspect something. We may not like that but, it's what Title IX allows right now.
