The other day some friends and I were shooting on family private property. A local sheriff who lived down the road stopped by to see what we were doing. Since I saw him coming, I put my rifle in the trunk.
He didn't ask to inspect the gun - and I am not even sure that he could, since I was parked right on the private property boundary, and not on a public road.
But he asked an open ended question:
"What are you shooting?"
I said "7.62x39."
If I had said "an AK" - it might have caused him to want to look at the gun.
The point is that what I did was subtle - I gave him a reason to leave, and didn't give him an excuse to escalate.
That is the kind of stuff that you learn when you get a little older - it's not necessarily an age thing - but age helps.
