WORLD: What can Australia's reaction to a mass shooting teach us about guns and gun control? | Watch VideoIn 1996, just 12 days after 35 people were killed in a mass shooting in Port Arthur, Tasmania, the government of Australia enacted strict gun control legislation, including a ban on the sale and import of all automatic and semi-automatic rifles and shotguns, and a gun buyback program. Since then, there have been only one mass shooting in Australia, and gun homicides decreased nearly 60 percent.  Correspondent Seth Doane talks with Australian politicians, and with a victim and gunowner, about the sweeping changes.
