I may have missed something. What, exactly, is the ethical violation alleged against the teacher here?

I saw the video made by the students that attempts to "prove" that the teacher said he wrote the test questions himself, but it makes an extremely flimsy case:

1) It's a statement made on Day 1 of class, long before the midterm test

2) He only said that he creates the test, but does not state that he authors the questions. One algorithm for creating a test is to select questions from a question bank, so this statement has no evidential value.

3) The only remaining "evidence" in the video is a statement where he said that "he may write" a question that even he may not be able to answer. It's entirely possible that he intended on Day 1 to author the questions for the midterm, but ended up using the above method for creating the test by the time midterms rolled around.

The students are very eager here to turn the tables here and display some righteous indignation to deflect attention back to the instructor, but they haven't yet managed to make a compelling case.
