So i got a reply from the AG's office
Unfortunately, the Attorney General cannot analyze, or provide legal advice to private citizens. As provided by statute:
The department shall administer and render state legal services, including furnishing of written legal opinions to the governor, legislature, and such state departments and officers as the governor may direct; represent the State in all civil actions in which the State is a party; approve as to legality and form all documents relating to the acquisition of any land or interest in lands by the State; and, unless otherwise provided by law, prosecute cases involving violations of state laws and cases involving agreements, uniform laws, or other matters which are enforceable in the courts of the State. The attorney general shall be charged with such other duties and have such authority as heretofore provided by common law or statute. Section 26-7, Hawaii Revised Statutes.
I regret that we are unable to help you.
So i went with the next step : I called the Govoners office to get an answer. I explained that i have asked HPD what the defintion is and they said they dont have one and that the AG's office would make that determination, I spoke to the AG's office and they say they dont have one but would make one up if they think some one broke a law ( WTF ). I expalined that they are refusing to answer the question based on the idea that they are prohibited by law from doing so. She said she would speak to the police department and get back to me, I again explained that i have spoken (via e-mail) to the current administration at HPD and that they say its the AG who makes that defintion. She said she will call the AG's office and find out WHY they wont answer the question and get back to me.
Looking at other state laws it is my opinion that there is a difference between detachable (for the purpose of reloading more ammo) and dissaseblable (the process of taking apart). one is an action that can be completed rapidly without tools, the other is a process that takes longer and requires tools.
.
Depending on what happens with the govoners office the only other option would be a lawsuit to force the AG's office to make a determination of the definition.
