Exactly, that's why the VP and AD got arrested - they lied.
I'm no lawyer, and I don't play one on TV but since Joe P didn't see this with his own eyes what steps would have the police taken? Wouldn't it have been necessary to have the grad asst be the complainant? (not excusing by a long shot, just wondering). Like if someone tells me they see a crime and I call the police and say that someone told me they saw a crime are the police going to care what I have to say?
