After a years-long hiatus, news just dropped in one of the major legal skirmishes. The Third Circuit threw out a challenge to New Jersey's file-sharing ban on Thursday. Just before that, California sued our guest for publishing gun files on the open internet.

That guest is Florida gun-rights lawyer Matt Larosiere. He joins the show to explain California's claims against him as well as the federal lawsuit he filed against California in Florida.

Larosiere accused California of filing suit for purely political reasons. He argued the state's claims are weak and its demand for nearly $8 million in damages is absurd. He claimed the state is effectively trying to impose its will on other states, even though neither he nor the other defendants ever went to California or intentionally shared information with anyone there.

He believes the Constitution is clear that gun designs and files are protected speech. Even if you drill down into more technical computer code associated with 3D printing of guns, Larosiere argued those files are protected by the First Amendment as well. That's why he was hopeful the test the Third Circuit created for judging the nexus between gun files and the First Amendment would actually help his case, despite that court ultimately dismissing a claim against New Jersey's file-sharing ban.
