The unthinkable happened Friday night at Guaranteed Rate Field when two women were hit by gunfire in the left-field bleachers during the fourth inning of the Chicago White Sox’s loss to the Oakland A’s. One day after the shooting, a Chicago Police Department investigation still had no answers as to how the incident occurred or where the shots came from. A shooting inside a major-league ballpark obviously would seem serious enough to stop the game and clear the ballpark.
