That doesn’t prove that not enforcing them would somehow make murder disappear, it just proves that you can’t absolutely eliminate a behavior. Every action has diminishing returns.
I can remove some of the heat from an object by putting it in the fridge. I can remove more by putting it in the freezer, but that requires more energy. I can remove even more by using more and more sophisticated scientific equipment, but I can never reduce the temperature to absolute zero. That doesn’t mean the soda in my fridge isn’t colder than one on the counter.
Perfect results aren’t obtainable except in trivial cases.
They’re enforced now but murder still happens.
