No one ever robs shooting ranges even though they are sites containing many expensive items as well as cash in the till because if they tried, everyone there has loaded weapons and would shoot them immediately. Apply this to real life. Increased gun ownership would create the "anyone could be armed" environment, and probably discourage violence by the .0000000000001% who consider it something they would do. So let's increase responsibility among gun owners and the number of responsible gun owners rather than disarming those who would protect us if someone should become an issue.
