Some things seem to never go away. One is the issue of abortion, another is the legalization of marijuana and yet another is gun control. What they have in common is the issue of personal choice versus considerable state intervention into people's lives. What they also have in common are the social and economic costs involved in exerting government control, costs that may well do more harm to society than if these areas were much less regulated.
Take the case of firearms. Any rational person would agree that there needs to be some control over lethal devices, but just like controlling a person's body or use of intoxicants, there are limits to effective control, and a point where the control itself causes more problems than it prevents.
