An assignment submission of one of my students matches "another student's paper" with a 100% match. Is there anywhere to go or anyone to ask for the name of that first student? It's one thing to accuse a student of plagiarism when you can demonstrate the web site which copied material is taken from. It's another thing to accuse a student of cheating if you can't document the name of the student he copied from in SafeAssign's submitted papers' database. Anybody been done this road?
