Interesting tidbit... as a CWP holder you are not required to tell an officer if you are carrying concealed. BUT, if asked to show a CWP, you are required to show that. So, you don't have to ID yourself... but if you are a CWP holder you sorta are... they don't need a reason to ask, just says if an officer asks to see it, you must present it. Reason I bring that up is that it isn't carrying concealed that triggers that requirement, it is having the permit. So if they want to ID you without your consent... they can ask to see your permit and if you have one, by law you must present it. Maybe I shouldn't be posting this because I don't know if any police that want to play games have realized that yet.
This only applies to WA State.
