The Background: Appearing at a Denver Post forum, anti-gun Democrat Congresswoman Diana DeGette confused clips and magazines and seemed to think that banning them would result them disappearing.
To your last question: What's the efficacy of banning these magazine clips? I will tell you, these, these, this is, these are um, ammunition, they’re bullets. So the people who have those now, they’re going to shoot them. And so if you ban, if you ban them in the future, the number of these high-capacity magazines is going to decrease dramatically over time, because the bullets will have been shot and there won’t be any more available.
