"This is them trying to make it seem like those who promote these laws don't like gun owners or are against them -- and that's nonsense," he says. "What people are concerned about is the ability of some weapons to mow down people, and the intent of some deranged people to mow down people.
"To me, the challenge to Dave Kopel and the sheriffs is, 'Do you want to make it easy for people to get hold of a gun that can mow a lot of people down?' They seem to want to make it easy. And because they're losing the public-opinion battle, they say we're discriminating against gun owners and casting aspersions as if we're blaming them for bloodshed. And that's just not the case. We're not discriminating against anyone. We simply want to make it more difficult to get these kinds of weapons, not easy."
Look below to see the aforementioned 9News report about the magazine ban, followed by the complaint against the gun laws and D.C. v. Heller, the Supreme Court case mentioned by both Kopel and Mauser.
