The moment they ask if you've been hunting and your answer is yes.....or any other indicators that would suggest you were hunting......they have legal authority to check firearms, ammunition, license, tags, etc. If those items are in your vehicle, they can be retrieved and inspected.
I guess thats the catch all, them being fish and game. Its still wrong, something about profiling and due cause and all.
Oh well, they cant do that here and I'm happy. Now if they want to pay the truck payment, I will let them search (since they want to act like its there property), otherwise, I want to see a warrant. I know that doesnt work, but you know what I mean.
