It has been nearly a year since Jared Lee Loughner opened fire on a public meeting held by Congresswoman Gabrielle Giffords. Mark Brodie talks to senior writer for the Tucson Weekly Jim Nintzel about the events of that day, and what Tucson is doing for the anniversary of that event.  Author and journalist Tom Zoellner, a friend of Giffords, sits down with Steve Goldstein to talk about his efforts to give context to the tragic Tucson shootings.
