Have you ever noticed how a few bad apples ruin it for the rest of us? For instance, it's really hard to find one of my favorite jelly snacks because someone choked on one of them and then sued the company for choking on it. Now the jelly snacks aren't carried anywhere. There's always those few who try to "beat" the system, but end up getting caught, which spurs the establishment to enact safeguards against future such threats, the costs of which get spread to the rest of us either through higher prices or no longer having access to certain goods/services.
The same goes for this plagiarism mess. Because of the inevitable idiots who try it every year, the rest of us have to sit through a seminar and get to listen to the people talk to us like we're babies getting warned about a spanking. I still maintain that these people should treat us like adults.
On a different note, I'm very very glad my last name isn't first on the list like Ms. Benson's is, since apparently Hovenkamp likes to pull the same trick every semester.
