Is this Legal?

To make this somewhat comprehensive, I’m just going to list the series of events that occurred.

-A friend of mine who is a RA at my college went to a party where underage students were drinking.

-Her boss learns about it through hearsay and starts demanding names

-The party’s host admits to it and is told either she gives names/people confess or she will be fired. So basically if the boss got more names, people would just be put on probation, not getting fired.

-To save the host, my friend and a few others confess that they were at the party; under the belief that they would all be put on probation.

-Contrary to what was told, when my friend goes to her trial, they tell her to give more names of residents who attended the party or she will be fired. She told them she didn’t know who they were so they fired her.

Why I think this whole process was entirely unethical, I’m wondering if there was anything illegal about it. The whole situation where they were pushed to incriminate themselves under the false pretense of a lesser sentance which they did not get does not seem right to me.

How ya doing, buddy?
