In 2005, as a high school senior, @lawler4ny flew from New York to California to attend parts of Michael Jackson’s criminal trial. The pop star had been charged with molesting a 13-year-old boy at his Neverland Ranch; the case ended in acquittal. J. Randy Taraborrelli, a Jackson biographer, helped get Mr. Lawler into the courtroom and recalled in his book that the young fan had been “so disgusted” by testimony against Jackson “that he couldn’t help but mutter something derogatory under his breath.” Mr. Lawler was removed from the courtroom, according to Mr. Taraborrelli’s biography, “Michael Jackson: The Magic, the Madness, the Whole Story.”
