The information was from the yearly AG's report. The reports, which started in 2000, have shown a yearly increase in firearms permits/registrations since it began. Per the report:
Firearm registration activity increased dramatically over the course of the twelve
years for which these data have been systematically compiled and reported. From
2000 through 2011, the number of permit applications processed annually climbed
136.9%, the number of firearms registered soared 170.3%, and the number of firearms
imported surged 148.3%.
As for the million guns in Hawaii, the report also states:
Although there is no way to track the number of firearms that permanently leave the state, independent
estimates made during the late-1990s by the Department of the Attorney General and the City &
County of Honolulu Police Department placed the total number of privately owned firearms in Hawaii at
roughly one million.
Other interesting facts include a rather constant 1.5% rejection rate (Long and hand-guns combined), a 4.5% approved but voided permits, and that 58.7% of permits were for long guns versus 41.3% handguns.
It also said 20% of the rejections were for mental health reasons. What I found interesting was that a footnote said:
Rejections for mental health issues or treatment can be satisfactorily
resolved with a verified doctor’s note stating that the applicant is no longer
adversely affected. While an original rejection cannot be overturned, a new
application may be submitted and the appropriate permit will be issued. It is
unknown how many applicants who are initially rejected for mental health
reasons successfully reapply for permits.
I would think that knowing how many of the initially denied permits for mental health reasons were subsequently able to successfully reapply for a permit. It also said 1 person was rejected for medical marijuana use and 2 were rejected for not being US citizens. But what I found interesting was the statement made about the issuance of concealed carry permits:
Eight private citizens applied for a concealed carry license in the City & County of Honolulu and were rejected for not meeting unstated criteria established by the chief of police.
Here is the language from the 2010 report:
Three private citizens applied for a concealed carry license in the City & County of Honolulu and were rejected for not meeting the criteria established by the chief of police.
It seems the AG is recognizing that the Chief is not sharing what criteria he's using to reject permits.
