If you're at home simply do not open the door.
+1. And don't bother arguing with them through the door. Just tell them to go away.
If you're on the street there are many ways to handle it. Michigan open carry on youtube has some good videos and audio. Make sure you know the law.
1. Buy and use an audio recorder.
This is fine in Nevada. In case you were wondering, there is no law in this state that prevents you from recording audio in public or private. Also, in cases where it is unlawful to record, this state only requires one person being recorded to know the conversation is being recorded. So as long as you know the recording is on, the one-person test has been met.
2. When confronted ask what your status is. Is it a consensual encounter or are you detained?
3. If consensual walk away, if not you may have to ID yourself, or tell the cop you have a gun, etc.
Agreed. If consensual, walk away. If you're being detained, NRS 171.123 requires you to identify yourself. NV Supreme Court Case Law requires only that you provide your name. You do not need to show ID, give your social security number, date of birth, address, or anything else. Just tell them your name, that's it.
There is no law requiring you to inform an officer you are armed, even if you are carrying a concealed weapon with a permit. You should not lie, but you are not required to answer, even if asked.
And since you're being detained, YOU ARE A SUSPECT IN A CRIMINAL INVESTIGATION. Let me rephrase. THE OFFICER IS LOOKING FOR YOU TO SAY SOMETHING INCRIMINATING SO HE CAN ARREST YOU. You were exercising your right to bear arms, why not go ahead and exercise your right to remain silent as well?
4. If detained you should probably do what the cops tells you to do and ask every once in awhile if you are free to go. I don't consent to searches and tell them so.
By all means, if a cop stops you at gun point, or orders you to put your hands up, DO IT! Live to argue another day. It's one thing to be dead wrong, it's another thing to be DEAD RIGHT. Just do as he says to keep yourself safe and no matter what, file a complaint later.
5. If you feel the stop was in error request audio, video, 911 calls, dispatch recordings, reports, etc through a freedom of information act (FOIA) request. Write a letter to the police stating why you believe the cop violated your rights.
6. If you feel especially violated file a 1983 federal civil rights lawsuit.
