Plaintiffs who sued Attorney General Gurbir Grewal over the right to distribute plans for 3-D printed handguns say allegations that they filed a phony document with the court doesn’t diminish the gravity of the state’s threats against their First Amendment rights.

A lawyer for the plaintiffs in Defense Distributed v. Grewal, writing to lawyers for the Attorney General’s Office on Thursday, made only an indirect acknowledgment of the state’s claim last Tuesday that a document filed in court appeared to be falsified.
