I can't imagine. Don't know enough about Hawaii (though I wouldn't think they have TOO many issues with violent crime
too nice).
I can, however, state the oft-quoted information that Canada and Switzerland both have similar per capita gun ownership to the US yet significantly lower gun crime rates. I can also tell you that I have done a partial historical analysis of Canadian (federal) gun control since the 1970s when it was first strengthened in a major fashion, and that there has been no evidence for an effect on gun crime or violent crime.
Violence is not a pathology of the tool, but of the person, be it individually or culturally. Guns do make it more efficient to kill another person, but they do not increase the likelihood that someone will attempt to kill another, nor does the fatality rate increase significantly beyond other means of weapon-involved assault.
