but generally the state lets a lot of things go, you do "press charges", that's why the cops ask if you want to press charges. the state doesn't go out and find every little crime out there and pursue it ruthlessly, for crimes like these they see if someone wants to press charges. if said person wants to press charges the state sees it as worthwhile to press charges, otherwise they might decide not to. so basically it's the people pressing charges. if the people report and then the state presses charges the people still did it.
