Well, the article is a little unclear on exactly what he may have done in the class on electrical currents. I thought it was important to report the student's allegations, but it doesn't sound like the Columbus Dispatch did any follow-up to verify the story or get more details (like, for example, what is this "device" used to mark students arms? Is it actually something electric? Or is the "device" something like a handstamp being used to demonstrate a concept related to electricity?)
