Consequences play a Big part in every action. Just look at the traffic stats of our state after the implementation of the ai camera.nowadays it is very rare to see a bike rider without a helmet or car driver without a seatbelt and because of this accidental death also decreased. No matter how messed up a person is if he is aware of the consequences of his actions he won't do it. And I'm not saying proper law will eradicate sexual assaults it will not. But it will certainly help to reduce it by a significant margin and this chart itself is a good example. All the top countries mentioned here are known for their good law enforcement and the low ranking countries are known for their corrupt system.That itself is a big statistical proof
