My nephew is a student a Millersville. The university warned them that if they so much as received a DUI conviction that they wouldn’t receive their teacher’s certificates. This story is entirely believable based on that.
Drinking beer from a plastic cup at a party is a far cry short of a DUI conviction.
It’s not a private school, but a public university. I’m not certain they’ll be able to make this stick.
That having been said, there is a LARGE segment of the current college-aged population that needs to pull their heads out of their asses. Online pictures can follow you forever. In my freshman class, at least three "young ladies" have either posted nekkid pictures of themselves, or a bf has done it for them. Eventually, someone that matters will find them.
