I’m a sheriff. Don’t flood the country with 3D-printed guns.

As sheriff of the fourth-largest and fastest-growing county in the nation, I know first-hand the threat such weapons pose to society. But it doesn’t require my 25 years of experience in law enforcement to know how dangerous firearms in the wrong hands can be. Downloadable guns undermine our federal and state gun-violence prevention laws, which help prevent people who pose a danger to themselves or others from accessing firearms. These laws are effective when law enforcement can conduct background checks and identify firearms through legally required serial numbers leading to a first point of purchase.

The ability to circumvent lawful and reasonable processes for purchase will undermine the work of all law enforcement. Our ability to trace guns recovered at crime scenes is a critical step in catching criminals and getting killers off our streets. Untraceable firearms will ultimately cripple investigations and provoke further violence by criminals.
