The 6-3 majority opinion written by Justice Clarence Thomas found the Justice Department was wrong to declare that bump stocks transformed semiautomatic rifles into illegal machine guns because, he said, they don’t “alter the basic mechanics of firing.”

The conservative majority that spent pages using circular logic to determine what a trigger is were wrong, and this quote is a prime example.

Edit: Hot damn, the dissent is an excellent tear down of how terrible the logic used in the majority opinion is.
