Wouter even the Dutch have a "duty of care" when it comes to "public" events.
If there is a cliff with a pathway along it and the occasional person uses it to commit suicide, that is surely that persons liability, but if some club organises a "hang glider" competition from that same point, then there is a duty of care for that club to ensure that the danger is "within an acceptable level", and if it isn't, and someone is injured, then they can be held responsible for the consequences - take the credit but also take the blame- (even though there are no cliffs in your “low lands”)
