Use case 1 An Engineer once reported the following: "At a prior institution I had the opportunity to share office space with a Professional Engineer (PE) who had an actual stamp from a former job where they worked at a nuclear power plant. I was often in classes with this PE and noticed that they never missed any points on homeworks or exams. One time the PE even drew and erased curves on an exam several times, not changing the curvature or inflection points, just re-positioning the line until it looked exactly like the solution. This was confusing because the PE could never seem to explain why they chose their particular solution strategy. In an advanced course, I noticed the PE's solutions were always identical to the professor's, even when multiple solution strategies were valid. Eventually the professor made the same mistake on an assignment that I had worked for days to point out as wrong to the PE Clearly something unethical is going on here. Am I bound by a Code of Ethics to report this suspicious behavior as this person is a full PE?" If you were in his shoe, how would you handle it
