I agreed in the abstract, but not in the specific (the specific professor was one of integrity, and sufficiently famous this was not an issue).

However, it's worth noting the universe is a cesspool of corruption. If you pretend it works the way it ought to and not the way it does, you won't have a very good time or be very successful. The entire legal system is f-ed, and if you pretend it's anything else, you'll end up in prison or worse.
