The Gun Tragedy/Gun Law Lag

Although my article today about gun control in the aftermath of the Loughner shootings is optimistic that it won't lead to much legislative action against guns, the Washington Post implies a different view with this chart showing the time lag between some gun-related crime and the legal response to it, including 13 years from James Brady being shot by John Hinckley to the Brady Law, and five years from Stockton schoolyard massacre to the "assault weapon" ban.
