Jared Lee Loughner is the accused gunman in this weekend's shooting in Tucson, Arizona that killed six and left 14 injured.

Dr. Jeff Gardere, a clinical psychologist and a contributor with HealthGuru.com, and Paul Callan, a criminal defense attorney and former prosecutor, discuss with T.J. Holmes.
