You seem to think that it's O.K. to do what you can get away with!
I just dislike environments where people can be punished on a false accusation, which describes the university environment today. I graduated close to 40 years ago, so it doesn't affect me personally.
There is a reason why we have a justice system with rules of evidence, where there actually has to be convincing evidence of a person being guilty before he's punished.
