Registration, too, is useless. The state of Hawaii has had a gun registry for 50 years, and not a single crime has been solved because of it. As the Washington Times reported in an editorial in 2009:
After all of the administrative expenses and inconvenience imposed on gun owners, police there cannot point to a single crime that has been solved as a result of those programs. Given Hawaii's remote island geography, this should be an ideal place to keep track of guns because movement in and out of the state is limited and legal importation is controlled. If registration is going to work anywhere, it should work there. Unfortunately, criminals seem to be able to get their hands on guns virtually anyplace in the world
