Some years ago I wrote to the police commissioner of the US Virgin Islands. Told him I intended to visit armed. No problem on his end. He did suggest I carry his letter with me when on the island, as it would avoid confusion should I run into one of his officers who was not familiar with the LEOSA.
I don't think it's fair to say "whenever something has gone wrong, LEOSA seems to be more of a defense in court than keeping you out of handcuffs on the roadside." We KNOW (within reason) the number of times that LEOSA has been used as a defense in court, but we have absolutely no idea how many times it has been recognized on the street and under what situations.
