Did School Have Duty To Stop Loughner?

Did School Have Duty To Stop Loughner?
Plenty of people had plenty of indication that Jared Loughner may have suffered from mental illness before he killed six people in Arizona last weekend.  But in the end, no one intervened, including students, teachers, and administrators at the community college he had attended.  
What responsibilities do universities and colleges have, beyond the borders of their campuses?
It's clear administrators at Pima Community College un Arizona knew something wasn't quite right.
Confidential police documents released by the college describe Loughner as creepy, very hostile, and suspicious.  Even then though, mental health experts say that's not necessarily proof that he was about to turn violent:
"We dont' know that we can predict those things with anybody, whether it's somebody with a mental health condition or somebody without," said Bill Dinwiddie, the CEO of the Mental Health Association."
"It's a tragedy; we need to respond to it, we need to look at what might have led up to it. But the difficult thing in all these situations is, it's unpredictable."
And so how much responsibility does the college hold?
Despite what happened Saturday, we don't know for certain that Loughner suffers from mental illness.
His behavior leading up to the shooting spree certainly would seem to indicate that.  And he's in the right age range-- schizophrenia sets in on average about age 20.  The college became so concerned about his erratic behavior, officials there expelled him, and told him he couldn't come back without a doctor's note clearing him.  Loughner never did get the help he needed.
"We can't force people into treatment unless there's that imminence of danger to self or others.," Dinwiddie says. "Then we can, and all the states have laws that allow them to do that. But again, if a person is saying I don't feel like I need help right now, we can't force them into treatment."
Loughner had no prior criminal record, and had not voiced any explicit threats.  But the college could have called local mental health authorities.
At Rutgers Camden and most other campuses, they'll also expel a disruptive student.  The dean of students says there's not much else they can do. But she says as a matter of procedure, they do notify county mental health authorities.
