I am going to say this again. The RCW's regarding wastage and game retrieval do NOT apply to national parks in WA. Why? Because the federal law states you cannot possess wildlife, plants, etc in the park. In this situation the federal law is superior to the state law. This federal law is NOT just in WA but in all NPS lands. If an NPS LE Ranger lets you retrieve the animal he is doing it out of good faith, and simply turning his head on the law. If he wanted to be 100% by the book the animal would sit and rot and you would not face charges.
Some posters are right in that there is a new superintendent at Olympic. Depending how involved they are they can really dictate how much discretion Rangers have. And if the superintendent says no retrieval then that is the policy until further notice.
