In a discussion about gun control policies, Aaron says, "Well, if you let politicians ban automatic assault rifles, pretty soon they’ll want to regulate all guns. And if you let them regulate all guns, pretty soon they’ll try to ban all guns. And once you ban all guns, then only the criminals will have guns and then there will be school shootings every day because the criminals won’t have to worry about else shooting them when they pull a gun." What kind of reasoning fallacy is Aaron using?
