Yes it is just dumb to think that holding a gun changes the human nature of a person, if Barak H. Obama is peacefull without a gun , he is probly also peacefull with a gun.
When Hawiians had no guns at all, before they met Captain Cook, they had wars and died in violence, but these wars were perfect , good , wonderfull things because the violence did not involve guns.
The number of guns percapata in the US has pretty much doubbled since the early 90s, while the rates percapata of violent death have fallen pretty evenly across the same place and period.
It really is dumb to expect that more guns in Hawii would cause more violence in Hawii, it is a position that has no science , logic or any kind of evidence involved, it only seems other than dumb to a reasonably intelligent fellow because he fails to examine it with science or logic.
