I thought it was illegal? There was certainly talk of a law a few years back. Can't remember what happened.
At least there was some arguing about it having a line between ok and not ok.
As others have said laws send a very strong social message about our overall values.
Plus plus with violence against children. All too often there's a feeling still about not interfering, is it for certain SS involvement etc is a big deal for families what if not that bad? Could have been a one off. Don't snitch.
Ideally people would always act. Even if not sure.
In practice it's well known people don't. And across a load of things.
This would mean if criminal imo-
People more likely to report as more concrete, against the law.
Police reports have to be logged, recorded, investigated (in theory). Not sure police would be best by themselves would need to be SS with police in background or something. Anyway that's an aside. I believe it would encourage reporting of incidents. Which would be a good result.
