There certainly is such a thing as being too aggressive in trying to detect cheating. It happened to my dad once but he cleared it up by re-doing the problem from scratch in front of the teacher. I think it's absolutely critical that any accusation of cheating allow the student to respond, preferably to a different teacher if the original teacher still thinks they were cheating.
