Facebook Just Explained How It Will Treat Websites That Share Blueprints of 3-D Printed Guns

"Plaintiffs have shown a likelihood of success on the merits of their Administrative Procedure Act claim," the judge wrote.

Gun control advocates lauded Facebook and the court's decision.

"If Cody Wilson is not stopped, then what we will find is a universe where the internet has plans to 3-D print any kind of weapon anybody wants," Brady Campaign co-president Avery Gardiner told Nightline, "with printers that make that incredibly easy for someone to do in only a few hours in their garage or in their living room."

The court's ruling, however, only applies to the sharing of data online. Wilson has developed a "computer-automated milling machine," which he sells for $2,000 and that has the capability of "carving" metal parts for firearms such as the glock and AR-15.

“This will take you a couple of hours, and it doesn’t require your constant intercession,” Wilson said of his in-home gun maker.

These homemade "ghost guns" can be generated anywhere and by anyone willing to purchase the necessary equipment.

“The term ghost gun refers to guns that really appear out of nowhere," Gardiner said. "We don’t have any register of who bought them, how they were sold."

“We have seen ghost guns used in shootings around America in the last several years,” Gardiner said.

Five years ago in Santa Monica, California, for example, several people were killed when a gunman wielding a "ghost gun" opened fire. The shooter had been barred from purchasing firearms due to mental health conditions, which prevented him from passing a background check.

Wilson acknowledged the risks but insists he is on the side of free speech and the Second Amendment.

“This isn’t just like playing games on your keyboard, right, on the internet? I’ve had customers arrested, right, in other states for owning guns when they shouldn’t have,” Wilson said. “But, again, [I’m advocating] that these are the necessary consequences of ensuring the people’s right to keep and bear arms.”

Wilson added that his goal is to help people empower themselves by giving them the tools to build their own weapons.

“A gun is power and this is the essence of this project… I'm actually giving people the means to create a power for themselves and I'm zealous to do that. That's real for me” he said. “People can misuse it, but it's power all the same. It's a conversation beyond good and evil.”
