When people talk about Hawaii,they are usually really talking about the island of Oahu.or Honolulu.(as tourists or off islanders that is their perception of Hawaii in general.) Each island in the chain has a slightly different gun or anti-gun culture,much as you would in various states or areas within a state in the lower 48.
My lady and lived in the islands for over 25 years,my 20 year old daughter was born there and in fact has a Hawaiian middle name.I lived there for a grand total of about 28 years.
It's a solid guarantee that if you try to generalize about gun control or firearms crime in Hawaii,your theories are likely to crash and burn in very short order.There are some things however that are clear or fairly well known.The following examples might be in order:
1) Before statehood the former queen had stated publicly that she didn't think "her SUBJECTS needed to own firearms" and only the police would need firearms to enforce the law.Of course that attitude spilled over into statehood and several generations of Hawaiians have a natural sense that guns are bad or abnormal.Since the turn of the last century the bulk of the firearms culture has been shotguns or long guns for hunting wild pigs.
2) Any firearm that enters the island must be registered within 10 days.A failure to do so I believe is a automatic class 2 felony.
3) The media,political and legislative attacks on firearms ownership is RELENTLESS.The permitting process is particularly onerous and a permit to purchase has a time limit of ten days even for a person to person transfer. If you fail to use the permit on time tough luck,no renewal,you start from scratch.(when we left in 2001 they were trying to put through a law to require your COMPLETE medical record to be submitted for the permit.In effect some snot nosed non-medically qualified clerk in the cop shop could disqualify you for virtually any reason.)
4) The police force are mostly locals and they know every inch of their patrol sectors.Profiling is not a theory,it is an operational certainty.I was very tight with a patrolman for years and had seen his "character file",a three ring binder containing the picture,stats,habits and arrest history of any hooker,homeless person,trouble maker or character of interest on his beat.I was in his file simply because I was employed as a locksmith.can you imagine being a bad guy and flying under the radar for even a brief period of time.
5) If you're a nasty felon where are you going to hide? You're on an island in the Pacific and if you plan to flee interstate you'd going to need a trans-ocean sailboat or a trunk full of great disguises and fake ID's just to sneak through the airport.Of course you're not likely to survive the gossip mill of the "Coconut Hotline" long enough to get out of your driveway without at least ten people knowing who what when where and how.
The whole law and order and crime scene is so different there I'm not even sure it follows the 95% rule and that's almost as certain as the sunrise.
