Transcript for Newtown School Shooting Anniversary: Gun Control Debate Goes On
And we move the next to gun violence, one month to the day after the tragedy in newtown, connecticut. Because the president announced today he has a blueprint for action.

Those that oppose any common sense gun control or gun safety measures have pretty effective way of ginning up fear. Reporter: While washington waits for the president's plan, things are already happening in the states. Today alone, leaders in new york, maryland and chicago moved forward on gun control initiatives and in connecticut, the families of the sandy hook victims called for a national dialogue on preventing mass killings.
