A Marjory Stoneman Douglas High School student who survived last week's shooting and her father appeared on "The Ingraham Angle" Thursday night to react to the revelation that an armed school resource deputy waited outside the school as the massacre unfolded.

At a news conference Thursday, Broward Sheriff Scott Israel excoriated Deputy Scot Peterson -- who has resigned -- for his failure to enter the school and engage the shooter. Israel said the deputy should have “went in, addressed the killer, killed the killer.”

"For him not to enter the building where harmless, innocent children were being shot is just disgusting," Ariana Klein, a junior at the high school, said.

Her father, Andrew Klein, agreed that it's "maddening" to learn that an officer with a gun was on the scene but failed to act.

"When you put your faith in the law enforcement to act to protect your children and then they fail to act, it's just inexcusable," he said.

He added that this highlights the other factors that contributed to this tragedy, such as the FBI failing to follow up on tips about the gunman.

"People need to be held accountable. This deputy's apparently been held accountable, but I think we need to continue to look at who's responsible for their failures to act in this circumstance."
