Friday's shooting at an elementary school in Connecticut could be especially traumatic for Coloradans, after this summer’s theater shooting in Aurora and the Columbine school shooting thirteen years ago. Mara Kalin, a psychologist at Aurora Mental Health Center, talked about that with CPR's Pat Mack. He asked her whether victims and others affected by the Aurora shooting should expect to have a particularly strong reaction to the tragedy. [Photo: CPR/MVerlee]
