So the police did not run a check that he was a prohibited person openly carrying??
It's not that simple. First of all, not every LE interaction involves an ID,
warrant, or background check. Second of all, often times the person's
records are not readily available. There are numerous holes in the system(s)
at play that sometimes will obscure someone's status. It's not as if they paint
a big red stripe on someone's driver's license or state ID when they're a
prohibited person. A little bit of digging by a LEO or investigator often
will expose that, however. Some of these people even somehow pass NICS
(either by fraud or by the system being broken)... of course eventually it all comes
back to bite them in the ass, usually years later, especially in anti locales. For
example, a license private investigator in MD got whacked with a FIP charge
because he owned firearms, and was involved in an assault 20+ years ago that
resulted in him getting a felony conviction. Basically his status was discovered
due to a fishing expedition of sorts by MSP.
