HRS §142-94
When you can kill loose rabbits or Belgian hares
Police officers and other people are allowed to kill any rabbit or Belgian hare that is running loose. If they do this, they cannot be sued for damages by the owner. But they cannot go into a fenced or inhabited area to do it unless they have legal authority or a warrant.
