My one regret, when considering my own case of someone with "grabby hands" (or tongue, in my case), is that I didn't make a bigger fuss.
My husband knows much better how to address this situation in this environment in a way that would benefit the woman attacked, while besting the villain. He is pursuing the expanded orientation/training option for potential victims, BTW, as well as refresher courses for potential abusers.
So, rather than actually do something about a known harasser, the solution is to have training courses? I'm sorry, but this sounds like no more than lip service to an ideal, while the university buries its head in the sand. I'm sure the training will say things like "Our university stands against sexual harassment." The problem is, they don't. All the training for the victims is not going to change that.
It sounds, BTW, that Professor Jerk doesn't need much refreshing on how to harass. Seriously, this sort of approach isn't going to make him sit up in the middle of the training video and go, "My goodness! I've been doing something wrong for years! I must stop it immediately." He will not be bested. At most, he'll get a chuckle out of knowing it's directed at him, but this is as far as anyone will dare go.
It's unfortunate that this university has not learned from the Penn State scandal that ignoring these issues doesn't make them go away, and that it's not fair to the victims to expect them to deal with it "tactfully" and "avoid ruffling feathers".
OP, I know this is not your workplace, and you do not have any real stake in what goes on here, except as any of us hate to see such things. But I can't help regret that universities have not learned by now that being "quiet and tactful" about such things is so very, very wrong.
