As nice as it would be to conduct a firearm sale in some random parking lot with no questions asked, we are in a tough spot. When conducting a sale of anything to a person you don't know, it's smart to meet in a public place, but inspecting a firearm in a parking lot is likely to bring some unwanted scrutiny.

As others have mentioned, I guess you just gotta do the inspection in such a way that no one driving by even sees what you're doing.

I would be really freaked out if the cops showed up and held me at gunpoint, asked for my license, asked if I had a CCW/was carrying. If no laws were broken, and it's obvious/apparent that no laws were broken, I don't think the cops have the right to ask for any of that - or more to the point, they can ask, but I have the right to refuse. We don't live in a "show me your papers" state... at least not yet.
