A few months ago, some conservative senators felt the need to kill a popular, bipartisan proposal on firearm background checks bill (H.R. 1565), and relied primarily on a single talking point: the proposal might lead to a firearm database.
The very idea of some kind of national gun registry was so offensive to them, that the legislation had to die at the hands of a Republican filibuster. It didn’t matter that the bipartisan bill had no such database. It didn’t matter that the bipartisan bill explicitly made the creation of such a registry a felony.
