National Rifle Association head Oliver North on Sunday blamed television and movie violence for the nation’s mass school shootings — and suggested metal detectors at every school could stop them.

In an interview on “Fox News Sunday,” North, the former National Security Council aide to President Ronald Reagan who became involved in the Iran-Contra scandal over aid to Nicaraguan paramilitary forces, said the carnage won’t be stopped by gun control.

"The disease is youngsters who are steeped in a culture of violence,” he said. “Nearly all of these perpetrators are male and they are young teenagers in most cases. And they have come through a culture where violence is commonplace.”

“All you need to do is turn on the TV, go to the movie,” he continued. “If you look at what has happened to the young people, many of these young boys have been on Ritalin since they were in kindergarten,” he claimed, referring to the medication commonly prescribed for children diagnosed with Attention Deficit/Hyperactivity Disorder.

According to North, “if you want to stop the carnage,” it’ll have to be done at school buildings themselves and “harden the place efficiently.”

“If that means metal detectors, you get five metal detectors,” he said.

He charged that student anti-violence and pro-gun control protesters are “being used by forces far bigger than they are to make sure … the Second Amendment goes away.”

“We know what [former New York City] Mayor [Michael] Bloomberg was up to,” he said, referring to Bloomberg’s financial contributions to gun control efforts.

“In our business, his creations have gone after you, me and everybody else,” he charged.
