This plays out constantly in the real world. We have several cases of it right here in my small town. It's not unique to this man or this university.
A woman is accused of taking her parents' assets. It is rumored that it was not legally done. They did not take her to court, but the talk starts and goes on. and on. and on. For decades.
A man is arrested for domestic violence. Evidence comes to light that causes all charges to be dropped. The accusations go on and on and on and on, publicly, constantly, even from the domestic partner who dropped the charges.
A town worker is accused of sleeping on the job. No charges are brought, but the accusations go on and on and on.
Yes, this is my question. At what point do you feel it become too much? Snide looks, chit-chat at parties, following you around, posting your face on posters around town, cornering your coworkers to tell them what you've done, yelling into a megaphone outside your house about how you're a criminal, etc. Is there a point at which you feel a line is crossed and they've gone too far?
