<p>That’s possible, but one can’t differentiate who is under-age and who is of age, unless you check their ID. Consequently, by allowing open drinking on campuses, a university is essentially helping enable under-age students to break the law. I doubt there are “campus monitors” who check student ID’s when they see people walking around drinking, or walking around with open cans of beer.</p>
<p>For those of age, it’s easy enough to go off-campus and walk into a restaurant or bar and buy a drink, or walk into a liquor store and make a purchase. They can easily and “more fully participate in the rights given them by the state and the nation” in that way, which removes the related issues w/regard to those under-age students.</p>
