Just something that crossed my mind and I didn't see it posted, could he have been a recruiter? Now I've never noticed a recruiter open carrying, but I'd guess that would give him the non-applicability coverage and if he's rolling around in his recruit-mobile then he doesn't have the personal vehicle issue. Also, he'd be going back to an office somewhere, not a base, thus no hassle as far as checking in and out go.
Granted, I really have no idea what I'm talking about, just throwing some thoughts out so those wiser than I can shoot them down.
