Supreme Court Justice Brett Kavanaugh started his new job on Monday, and heard his first case on the nation’s highest court Tuesday. And he hit the ground running. Hearing arguments over what should be considered a “violent felony” under the Armed Career Criminal Act, Kavanaugh asked nearly as many questions as Chief Justice John Roberts. Speculation was that he might lay low at first, but Kavanaugh—who has 12 years of experience as a judge on the D.C. Court of Appeals—did the opposite. No protesters managed to crash the proceeding.
