The president of a Christian university encouraged his students to get concealed firearm permits so they could prevent the next mass shooting from happening there.

Jerry Falwell, Jr., head of Liberty University, a Christian school in Virginia, invoked the mass shooting this week at the Inland Regional Center in San Bernardino, California. Fourteen people were killed and 21 were injured in the attack, which was carried out by a husband and wife who claimed loyalty to the Islamic State.

Falwell criticized President Obama for urging gun control in the wake of recent shootings, and made it clear he was armed during his speech at a convocation Friday night.

“It just blows my mind when I see the President of the United States say that the answer to [San Bernardino] is more gun control,” Falwell said. “If some of those people in that community center had had what I’ve got in my back pocket right now—”

He encouraged people to carry guns so they could ” end those Muslims before they walk in and kill us,” Falwell said.

He then said the university offers a free course to help get a concealed carry permit.

“I just wanted to take this opportunity to encourage all of you to get your permit. We offer a free course. Let’s teach them a lesson if they ever show up here,” he said.
