I like the idea of legal ownership of guns. Banning gun ownership won't stop people getting guns, if people really really want guns and the state prohibits gun ownership, they'll just turn to the black market in the same way many criminals do. At least if the state keeps a registry of gun owners there can be some minimal controls made.
