Maine Gunman's Warning Signs: "Capable" and "Trained to Hurt People"

Three months before the alleged Maine mass shooter opened fire, Robert Card told New York State troopers he was "capable" of doing "something," prompting concerns about his mental state and behavior. Despite being taken for psychiatric evaluation and treatment, Card would later allegedly carry out back-to-back shootings at a bar and a bowling alley in Maine. Newly released police body camera footage shows Card's concerning behavior and statements, as an independent commission investigates the events leading up to the mass shooting and gains subpoena power for its probe.
