PASADENA, Calif. — CBS entertainment chief Nina Tassler says the network is sensitive to concerns about violence following the Connecticut school shooting, and that everything it puts on the air is appropriate.

The network's prime-time schedule is dominated by crime procedurals, many with gruesome murders. Tassler said Saturday that CBS' paradigm is that the good guy always wins and the bad guy goes to jail.

She said NBC entertainment head Robert Greenblatt made a "huge mistake" in singling out the CBS show "Criminal Minds" for its violence. She said, however, that it's not a show for children.

Tassler said the shooting of school children in Newton, Conn., has shaken her and others at CBS and they've come to work with a renewed sensitivity.
