Should a radical activist be allowed to publish instructions for using a 3D printer to create a fully operational plastic handgun? That’s the question facing U.S. District Court Judge Robert Lasnik, who has said he will hear arguments this Friday in a case that pits freedom of speech against public safety.
The activist, Cody Wilson, has been trying to upload those plans for five years but had been prevented from doing so by the federal government. He nearly succeeded last month, after the State Department withdrew its objections. But
Lasnik issued a temporary restraining order
If Wilson wins, it is easy to conjure up the evils that might result: an endless supply of untraceable guns that could be smuggled past metal detectors at airports and elsewhere and that could be printed out by thrill-seeking adolescents once 3D technology becomes sufficiently cheap and reliable. But as an equally fraught case from a generation ago demonstrates, the concerns raised by dilemmas like these invariably prove to be overblown.
In 1979,
The Progressive

Publishing instructions on how to build a nuke might not seem strictly necessary. But The Progressive’s editor, Erwin Knoll, defended his motives. In an
essay
Like Judge Laskin in the plastic-handgun case, U.S. District Court Judge Robert Warren issued a
temporary restraining order
In arriving at his decision, Warren relied on two Supreme Court precedents. In
Near v. Minnesota
Judge Warren was well aware of his responsibility as a guardian of the First Amendment, and he urged the two parties to come up with a voluntary agreement that would have allowed The Progressive to publish while omitting the most incendiary material. Before he could issue a final ruling, though, the matter was rendered moot when a newspaper in Madison published a letter containing substantially the same information as the Morland article. The case was dropped, and The Progressive published the Morland article under the headline
“The H‐bomb secret: How we got it — why we’re telling it.”
The government’s and Judge Warren’s concerns proved to be unfounded. The information revealed by The Progressive has never been traced to the development of a nuclear weapon, even though terrorist groups such as Al-Qaeda and ISIS would love nothing better than to develop their own nukes. Building nuclear weapons involves a lot more than reading an article about it.
The threat posed by Cody Wilson’s plastic-handgun instructions is less existential but also more immediate. Though buying guns illegally (or stealing them) is easier than printing them out today, that is likely to change over the next few years. But the way to ensure public safety without violating the First Amendment is to outlaw activity, not speech. Plastic handguns are illegal unless they contain metal components. Guns without serial numbers are illegal.
“The distinction between regulating information about guns and regulating a tool that would automatically allow someone to manufacture a gun matters,”
writes Boston University law professor Andrew Sellars
By temporarily preventing Wilson from publishing his blueprints, Judge Lasnik has already violated Wilson’s — and our — First Amendment rights. Let’s hope that on further reflection he comes to understand that when we try to ensure safety by suppressing free speech, we end up with neither.
