San Antonio Spurs Head Coach Gregg Popovich called the Second Amendment a “myth” and called for politicians to do more to prevent school shootings during a fiery pre-game press conference in Dallas on Sunday. Popovich’s remarks, made before the Spurs’ 138-117 win against the Dallas Mavericks. Popovich began his monologue — posted on Twitter by Dallas Morning News sports reporter Brad Townsend — by citing a quote from Tennessee Sen. Marsha Balckburn following the mass shooting in Nashville two weeks ago, in which she said that her office and other government agencies were “ready to assist.”
