IIRC when I was there, if I had moved my collection of firearms from OK to the island (legally) than the number of (legal) civilian owned guns would have risen 5-10%Was in Grand Cayman in February; guy we talked to said they had guns and gun crime there, but he said it was very hard to get guns (legally), and there was like a 100% tax on firearms, and 200% tax on ammo, if I remember right. Told my wife that seemed stupid, at least the ammo part; if I was bent on killing someone, another $40 or $50 wouldn't change my mind.
I also keep dedicated bags for travel. American arrogance (and in this case possibly ignorance) is what gets us in trouble elsewhere. We think no one's rules apply to us, Americans being "exceptional" and all. Too bad the rest of the world doesn't feel that way.
Considering all 4 islands together are about the land area of the city of Tulsa, that's a low number for the place.
