A father of a victim of the Columbine shootings responded to the recent shooting at an Amish school, said abortion has cheapened people’s view of life.

CBS News featured Denver resident Brian Rohrbough, whose 15-year-old son Daniel was killed in the Columbine massacre. In his interview, aired nationally on the program, Rohrbough said abortion has caused a dimmer view of the sanctity of human life.

“This country is in a moral free fall. For over two generations, the public school system has taught in a moral vacuum,” he explained. “We teach there are no absolutes, no right or wrong. And I assure you, the murder of innocent children is always wrong, including by abortion.”

“Abortion has diminished the value of children,” Rohrbough, who is a member of the board of directors of Colorado Right to Life, said.
