I see what your getting at. I agree fully. I was trying to find a way that you could "reasonably" articulate the situation to where a terry stop would be appropriate.
Hear me out. Im not trying to work words into a way to violate rights. Being as unusual as it for a man to carry a rifle slung over his shoulder at 130 am down the main drag (i recognize not illegal in any way), given recent events in our society (again in no way makes it illegal), would it be reasonable to think a crime may be about to be committed when the person refuses (only at first in my situation) to identify himself or show any handgun permit?
Doesnt the totality of the circumstance tend to lean toward justifying a terry stop where he would be required to identify?
Im just thinking out loud. Im here to learn and do my job more effectively.
Terry stop isn't based on a hunch. You need to articulate some criminal activity you believe to be afoot. Open carry of weapons in the wee hours is unusual but not criminal. If you can plausibly connect this to something else, e.g., it's 1:30 and he's carrying weapons openly outside the house of his estranged wife who has a NCO. But the problem here is his location.
You can detain briefly to check the LTCH. That's not a consensual encounter.
On the other hand, if he does consent to stop, present ID, etc., you can check that.
You can always ask. Beyond the LTCH, you can't force anything more. If in the course of the LTCH check you develop reasonable suspicion, then you can prolong the stop. But not solely on a hunch.
In your situation, I would be curious why a person, assuming he had an LTCH, would refuse to show me same, or in the alternative give me his name so dispatch could check on it. This fact is curious, assuming he believed himself to be a law-abiding gun owner... But I wasn't there.
I would be interested to hear what the prosecutor's office tells you.
