Depends what you are trying to achieve - If you let everyone go, you will never nail the culprit.
We had a brand new 737 at AMS which had the toilet mirror vandalized in flight by a diamond - huge rude letters right across. The captain let everyone off. I think I would have had the police come first - strapping big Dutchmen with holsters - just to make the point.
But there - Captain is paid to make decisions to the best of his judgement.
Gonna have to edit this - Mc Gloff haven't you heard of any crashes caused by toilet waste fires then?
