Have you ever accidentally snitched on someone?

I'm almost done with my degree , I'm a uni student.
I have a classmate in her 40s who was cheating on the 100 question test today with her phone out.
Although I know these things are common, I couldn't believe my eyes !

Before I proceed ladies and gentlemen,
Let me ask you this ,
Do you want a future nurse caring for you that cheated her way to a degree? Think about it , when your life is in her hands.

Anyway, so class finished. I started talking to one of my classmates about what happened.
I heard a "What?" behind me.
It was my professor she wanted to know the persons height , clothing , hair color etc.
She pulled me back into the room to tell her.

In a sense I felt horrible.
Because you know , nowadays people act like the person who snitched is worse than the person who committed the wrong doing.

Lol.

Pretty sure if I made this a question like, "Whats your favorite color?" I'd have a million answers by now.
