"BTW we don't have a "right" to be in university libraries."
We do if we pay tuition to said university.
"
We do if we pay tuition to said university."
Not a right, its a privledge. All based on you following the university rules.
And if you pay tuition to said or any other university, you're paying for campus security.
Campus security POLICY in this instance was to announce that ALL patrons to the library were to have ID's checked at that point in the evening.
ID's are checked to ensure the safety of other said students.
This gent was repeatedly asked for his ID and refused to show it.
In your opinion - should campus security have just left him there?
What if he wasn't a student? What if he was just Joe Schmoe waiting to follow your daughter out the door?
