A Stanford University law professor took the view that the Second Amendment permits strong gun control, telling the crowd that “restriction has to be at the core” of the right to carry a gun.

John J. Donohue, a member of the Stanford Law School faculty, made his remarks during a debate with attorney Donald Kilmer, an adjunct professor at Lincoln Law School of San Jose.

“I support the right to self-defense,” said Donohue during the debate, according to The Stanford Review. “But that doesn’t mean that you have a right to high-capacity magazines.”

Donohue explained that the Second Amendment must be interpreted in historical context. The founding fathers had no idea how powerful–and destructive–today’s weapons would become, he said.

He also criticized the argument that the right to bear arms was necessary for American citizens to guard against tyranny.
